These will probably get in to help fill the number. They are very good tracks with good AI, but all have a few issues that make them less comfortable for a beginner:
Motherload 1.5
RCA Jam (maybe)
Rocky Mountain Way
SPs Outback Trny
204WHIPPET
Construction Zone
Zoon Moon
So that takes us to 60 tracks, the ones with an asterisk (*) are really very good AI wise.
