I'd like to buy some new Real Tracks. I can see which ones I have in Band in a Box, using What Band-in-a-Box add-ons do I have. It looks like this for Real Tracks.

RealTracks sets in C:\bb\RealTracks\ : 1- RealTracks 1, 2- Country Ballad, 6- All Metal!, 8- Country Folk, 10- All Blues (Shuffle), 11- All Bluegrass (Rhythm), 13- Older Jazz Swing Soloists, 14- Mainstream Swing - Jazz Rhythm Section, 16- Bossa - Rhythm Section, 17- Bossa - Soloists, 18- Jazz Ballad - Rhythm Section, 20- Dual Rock Guitars, 25- Pop Swing 8ths Bass 1, 26- Pop Swing 8ths Bass 2, 27- "Dreamy" Pop Guitar, 28- Jazz Waltz, 33- Bluegrass (Medium Tempo), etc...

But how does that info relate to the Real Tracks info displayed on the web site. For example:
Jazz RealPAK Vol 1 – $79
Includes RealTracks Sets 7, 13, 14, 15, 16, 17, 18, 19, 28, 29, and the Jazz RealDrums from Sets 1-20. Acoustic Jazz Bass, Bossa Rhythm Section, Jazz Guitar Comping, & more!

Thanks,
Mike
