personally i think seba is such a good producer you should just type his name in to chemical or redeye and listen to everything he's done then choose which ones you like, or maybe which ones you dislike because that would be easier
I love Seba's work. No one else quite does a fat liquid bassline like him. Ive constantly got at least 1 seba track on constant rotation on my decks, I think its about 4/5 currently. heh.
Some of my faves are:
Painted Skies
Crockett
Never Let You Go
Forever
I could go on, but you'll have more fun finding the rest yourself
Definitely Snow, Don't You Love Me Anymore and Keep Me Waiting. Gotta backup that statement above though that in fact every tune he has done is pure gold
