I spent some time this week building a wishlist on Puretracks, basically an exercise in "what do I need to buy to build my dream MP3 collection". I ended up (so far) with the following artists. I guess it's kind of my "favorite pop/rock music" list.

Yes (not everything, but a lot)

Jon & Vangelis (the two they have)

Vangelis

Leonard Cohen

The Moody Blues (mostly the sixties-eighties stuff, I wasn't crazy about their albums from the nineties and noughts)
