Listen to the Music - Doobie Brothers

Thanks to your lesson I learned "Listen to the Music" rather fast; however, I want the back up track. How do I obtain that one, plus others?
Thanks for your time!

I found a site (most have probably seen it) called guitarbackingtrack.com Some are pretty good, others are not. I picked up back in black by ACDC and it was about a 7 out of 10.
