JJJ,
I agree with with idea of more advanced sorting/searching (exclusions and additions), as well as many of your other opinions and comments... This time, I must admit, the contemporary POP request is a bit beyond my understanding. What are we talking about? Premade styles? Demo songs? Rts or Rds? Specific instrument loops? Not trying to tease you. Really trying to understand...I have a general idea of what pop music used to be, before "home" computer music exploded (from bout 1920's to very early 2000s) 

Maybe I am completely wrong, but it seems to me a good chunk of contemporary POP is emphasized  mainly on synth based sound design, short sample phrasing, arpeggios and "beat" making with a hint of 3-5 "popular" FX or FX chains. Is this the type of RTs being requested? If yes, or at least somewhere in the range... Then I believe the best bet would be to request PG to complete development of User Tracks, to include shots, holds and other good things. That way you can use software workstations such as Halion or Kontakt, to make all kinds of contemporary User Tracks that will fit the workflow of BIAB and follow all other stuff(chord, bar changes, etc), just like regular RTs. But the beauty of this approach is that it would be easier to change something. For example completely different sound, or rhythmic syncopation to better fit the composition you are making, because you can have a secondary "User Track" project opened in DAW and create endless User Tracks to your liking and mix these with RTs that PG music provides.

Just to prove my point. For laughs, thinking about this I did a very simple synth/arpeggio 1 minute User Track in under 20 minutes from start to finish. I know it is junk, but it proves the concept. Here it is:

Unzip, copy "pop" folder to bb/RealTracks/UserTracks Open BIAB select UserTrack from mixer, navigate/search: pop. It works with even feel tunes with tempo around 110. Now that I have project setup in DAW, I can have this UserTrack, sound completely different in under 5 (five!) minutes. This was done using a 1 minute POP template.  You can get a 30 minute template from PG.

P.S. Jim F. Yes, I remember points you made about naming. I was aiming at speed, this is not something one would keep, just a listen and throwaway thing. I promise, if I do something more serious, I will name it right smile
