there's a wide assortment of jazz that suits all sorts of tastes, and even the term jazz itself is really subjective. Only reason i mention that is that it's hindered my search...hehe
Got to find that sweet spot. If your looking for that stuff you hear in restaurants, movies, malls etc. just do yourself a favour and look for a jazz collection torrent...you'll find plenty of what your looking for.
otherwise if your on youtube just do searches on the big names such as billie holiday, ella fitzgerald, charlie parker, john coltrane, dizzie gallespie, duke ellington, cab calloway, thelonious monk, miles davis, bill evans, louis armstrong, etc. I'd find all sorts of gems in the 'related' bar at the side, alot of them unrelated to the artist of the video.
I think a good idea would be to post some tunes up that you particularly liked so we could help you out better.
