I want to add one more vote for non music. Reason? People have different tastes in music. I find that most music on tutorials is distracting, and I usually turn it all the way down.

Understood.  It's one of the reasons I asked.

Been using Sonic Fire Pro, which has all sorts of different styles, the reason being you can make the music to the exact length you need. Very sweet.

But if you like head banging stuff, you won't hear that on my tutorials. LOL!!!  I do have some good rockin' stuff though.
