I thought this would be a more appropriate forum to ask if someone else knows of other sites that sell or give backing tracks.
Here is the post about backing tracks from the other forum:
Under ---> MP3 INSTRUMENTAL ---> all fixed stereo songs. (the song $199)
Under ---> CUSTOM ACCOMPANIMENT TRACK ---> you can download the individial musical instrument tracks, or mix online and then download. (the song 2.99)
We have over 30.000 songs.
