So, I submitted this about six weeks ago and it got a well-deserved trashing (http://news.ycombinator.com/item?id=293699).

I've spent a bunch of time on the site's algorithm, plus there is a load of new stuff: playlists, automatic recommendations, links to get more information about artists.

I'd love to get some more feedback from the HN community.

well, as somebody who has been in this space before and left it to pursue other music opportunities, I think you're off to a great start mary.

I wasn't able to get music to play on quite a few tracks (the majority actually), but without any sort of progress bar on the download, it wouldn't be apparent to most people what is happening, so I think that would be one of the first things to do.

I didn't go through your code, but have you hidden the flash player somewhere? or are you using a javascript player?

Whatever, I think showing a player inline (kinda like you are now, but with more controls) would benefit you. At the least, you need a 'progress bar', and the 'hear' should be linked to start the track too, as that is what I tried clicking on, not the play button.

I'll be keeping an eye on your progress mary. Best of luck to you.

maryrosecook10• 18 years ago

Yes, I agree with you. The player does need a loading progress indicator. I also need to be more aggressive about culling tracks that are hosted on slow servers, or have been removed.

I use JavaScript to control a little offscreen flash player.

Thanks so much for your feedback.

What it really needs is more data, anything obscure and you get no recommendations.

maryrosecook10• 18 years ago

Niche music is one of my main focuses. For obvious reasons, the site is is good for the sections of music I like. Could you tell me what genres/niches/bands you were trying? I'd love to expand the index to include them if I can.

Thanks very much for the feedback.

STHayden• 18 years ago

I couldn't get results for Mike Viola, Candy Butchers, Fountains of Wayne, Julia Nunes, Ghosts & Liars and The Salteens

cheers!

I like your site. It has potential. How bout include some album art next to the artist descriptions?

I think you can also UI redesign. Starting having some buttons and graphics.

good luck!

maryrosecook10• 18 years ago

Yep, album art is a real nice idea.

The UI is something I am thinking really hard about. My skills are in coding, not UI/design, so I'm learning as I go.

Thanks for the feedback.

It's really cool. I don't love the colors though, I'm not a big red fan (while I wear a Man U jersey...oh well:))

got 2 (way off) recommendations for my favorite band.

my opinion is that this space is wayyyy too crowded (huge players involved) and to take any market share seems impossible.

maryrosecook10• 18 years ago

Which band was that?

mstefff3• 18 years ago

dream theater

The Postal Service:

  Amazon: Death Cab, The Shins
  iTunes: Imogen Heap, Feist, M.I.A.
  Perceptron: The Knife, Dntel, Bright Eyes

Eric B and Rakim:

  Amazon: EPMD, Big Daddy Kane, Public Enemy
  iTunes: EPMD, Boogie Down Productions, KRS-One
  Perceptron: No recommendations

Fleetwood Mac:

  Amazon: Journey, Bob Seger, Steve Miller
  iTunes: Rod Stewart, Eric Clapton, The Doobie Brothers
  Perceptron: Vetiver, The Beach Boys, The Everly Brothers

Sepultura:

  Amazon: Pantera, Slayer, Metallica
  iTunes: Soulfly, Machine Head, Fear Factory
  Perceptron: Moonspell, Soulfly (x3), Fear Factory

In none of these head-to-heads does Perceptron do the best job (the Dntel pick ties it with Amazon's Death Cab pick). I can intuitively guess that iTunes will do a better job of recommending for me than your website, because millions of people's buying habits make iTunes smarter every day.

It's not just that this space is crowded; it's that it structurally resists your entrance. You need features, lots of them, compelling features, or this isn't going anywhere.

Also, you're trivially XSS-able:

http://theperceptron.com/recommendation/artist/h%3Cscript%3E...('hi');%3C%2fscript%3E?h=true

Finally: "astute music recommendations" is a terrible tagline. It doesn't convey value. It tells me why you like your code, but not why your code matters to me.

maryrosecook10• 18 years ago

I see what you mean about the tagline.

Thanks very much for doing those side-by-side comparisons. I am not a fan of any of the bands you entered, but, to my ill-informed eye, the recommendations don't seem too bad. Which ones were off the mark?

And thanks for the heads-up on the XSS exploit. Will need to sanitise my URLs more thoroughly.

Thanks very much for your feedback.

Postal Service: Indie pop; you did fine, but not better than the majors.

Eric B and Rakim: seminal NYC hip hop; guessing classic hip hop is a blind spot in your data set.

Fleetwood Mac: mainstream classic AOR; Vetiver? An indie folk band? The Beach Boys are similar only as contemporaries --- also, not a very useful recommendation, since there are 3 different Beach Boys your recommendation could be keying on, two of them execrable.

Sepultura: insider-y mainstream metal; you did fine, I guess, but not better than the majors.

In two cases your recommendations are bad, and in two cases they're just not excellent. But if any online music retailer will do this for me, why would I use your service? To listen to some of the music online?

You should consider:

* Allowing people to upload their entire iTunes library files so you can analyze them and make targeted recommendations to stuff they already own.

* Allowing people to vote on the recommendations, or doing something "social" (gag) to let people adopt recommendations or biases from tastemakers who care about this stuff.

* Link to or repurpose content from Wikipedia to give more background for the artists you're displaying.

It still seems like this app is really just 10% of what Last.fm or Pandora already does.

I don't like the simple, all text interface. I think an app like this needs a clean but graphical interface. Take a look at this screenshot: http://skitch.com/rksprst/3t9q/the-perceptron-astute-music-r...

Am I supposed to understand any of the text there? It looks like a bunch of random works thrown together. No human will ever read that. No offense but this display reminds me of those "crack/serial" search engines that just list a bunch of random programs in alphabetical order just for seo.

I think you have a neat idea. But please get a designer.

maryrosecook10• 18 years ago

Yep, I do need a designer.

The band descriptions are taken from Wikipedia. My parsing code needs work.

Thanks very much for the feedback.

rsheridan6• 18 years ago

There ought to be a way to just upload a list of the music on your computer.

maryrosecook10• 18 years ago

Yep, I have investigated this. It's lower on the list of priorities because my focus is to make the site work when it knows nothing about the user.
