I agree. Beatles songs are great for this. But I would say don't stop after learning a few simple songs, always keep learning more. one new song each week maybe. Keep in mind that most of the musicians whose music you are learning probably learned this way as well. of course, if you want to learn classical or play like Coltrane, you'll need to learn the theory.

The very first Swift question has a partially incorrect answer. It says that "var array2 = array1" creates a copy of array1. But it's incorrect because a copy isn't actually created until one of them is mutated.

Actually bands hire the musician who has the look, sound and personality that fits whatever they're going for. Most of them don't know any theory beyond blues and folk chords. They might test them by jamming with them, but the decision has nothing to do with musical skills. So it's actually very similar to hiring in tech.
