true but it all depends on who makes what happen. does owl city make his own beats/samples/electronic compositions? the same also applies to huge artists like Kanye....i for some reason doubt Kanye comes out with his own samples but rather has a high level producer come up with them for him.
I think it's pretty well known that Adam Young does all of this on his own, or at least has in the past. He was self-produced on his first two albums, and I think even a bit on Ocean Eyes
, if not all.
I'm not a huge fan of Kanye, so I'm not sure about him, but I know he's an integral part of beat making for his own music. He probably works with other producers, but hell, Brian Wilson and Paul McCartney worked together and came up with ideas for one another..didn't make them any less of musicians, but rather all the more stronger.
You could even go with the idea that solely singing, and creating a lyrical melody over a manufactured beat is still being a "musician," as the voice is still an instrument. Acapella music is still music.
