Well, that's what I do...save all the "Real Stuff" as MP3's, including styles, soloists, real drums, etc., and jam live with the many, many groovy material, as with a live-back-up-band. I'll do more of "it" when I get hold of 2010 and the new USB harddrive for $139.

But I've also been a proponent (buyer and user) of Brad's Real Book On-Line, which is a compendium of the greatest hit jazz mp3's in existence...as far as I am concerned. As backing for a jazz singer and jazz guitarist, as I am (and I also have about $20K in keyboard synths and modules/studio components as well as Sonar)...I love nothing better than to jam along with pre-recorded masters of jazz and jazz ballads, artists and such!).

I've always loved the special gratification of playing, as a single performer, in a jazz bistro environment...
the addition of Real Band/Real Drums in specific styles is a Godsend, and in addition I love to listen (and jam with a meriad of jazz artists (via MP3 backing with the original hit recordings)...live...the sound of all of this is truly remarkable...there is no audible difference between real and MP3 recorded, with today's sound systems. If you've got a good soundcard...or better yet, external synth modules or keyboards that never fail as software, you can have your MP3 Cake...and, eat it too...sucessfully!! Of course you probably are already aware of the "vocalists" hardware and software that can remove a vocal or solo track you would rather eliminate.

Whether you're into audio only or midi mostly, or a combination of both, BIAB will get you home fast!!
