Bowie, Hendrix and The Beatles are all good places to start. If you like the Beach Boys I emplore you to listen to Dennis Wilson.
Personally, I would've added Faith No More, Love, The Band, Dylan, John Martyn, Anticon, They Might Be Giants...and many others to that list.
Variety is what you want!
it's the spice of life, especially where music is concerned. I will go as far to say I don't like a tune at all, but the melody of the vocals is pretty cool. So I will dislike a tune overall but like small aspects of it a lot.
