+1 for Midi-hits. I've bought several... they're very good.

in comparison...
I've wasted time downloaded thousands of disappointing free MIDI files...
I've wasted time sorting through them to find something usable...
I've wasted time trying to fix bad drum tracks or incorrect notes...
I've wasted time trying to learn how to make the whole track myself....
I've wasted time trying to learn a variety of different software packages to help me make my own tracks...
I've wasted time searching huge archives trying to find the right drum pattern, style or groove track for a song...

Given the goal of assembling a gig's worth of backing tracks to startt performing ASAP:

If I were starting from scratch today, I would make more progress for less money and in a shorter period of time by simply buying high quality tracks from this place at bulk/sale prices

Given the goal of creating original music AND creating backing tracks for covers:

The tracks I'm making now with RB and BIAB sound better to me than the MIDI-HITS songs. I'm having fun making them, and PGMusic's products also open doors for creating original music. You can't buy that from MIDI-HITS or anybody else.
