Sorry if this has been asked before, I searched but didnt find anything similar. I'm guest playing at local churches (and being paid for it), am I allowed to play along with accompaniment tracks that I bought? I have a few from Brasstrax.com, and a few out of Alfred's Top Praise & Worship book/CD, all purchased, but does that give me the right to perform them for profit? If it matters, I dont use the sheet music that came with any tracks, I just play along, with some gentle inprov along the way. What about recording them? Not for profit, but just making home recordings for giving away to a few people who want to hear them? I have a few such recordings on my myspace page (see sig), should I take them down?
