Ask HN: Looking for the Shazam for Song Fragments

Yesterday I was listening to Perfect Circle's "The Noose" and I noticed a particular pattern I really like about this song that I remember listening to in other songs, but there's no way to look for them.

It'd be great to have an app which receives some short fragment of a song and returns a list of songs containing similar sounding patterns.

Do you know if something like this already exists?
