Yes, I'm buying from MIDI Hits. I tried the MP3s, and decided they're not for me.

1) I'm a guitarist, and they all have the guitar parts, which I can't get rid of.

2) I can't change the key (my vocal range is lower than most lead singers).

3) I can't turn the bass off, or keyboard parts, drums, etc. if one of my friends wants to come over and "sit in."

So, I'm probably gonna stick with MIDI - I like having control of at least one thing in my life :-)

And again, I'm glad so many knowledgeable people are out there to help if I need you. Thanks all.
