"SONGS AND BACKTRACKS" is a CD-ROM that contains some 700 song files, some of which are the same song written out in different keys (the ones I often use in lessons).
Having worked through the courses, the learner can now go through this collection to see which songs are familiar, and which of those have easy chords.
There are also 189 mp3, and 328 midi backtracks, as well as a program that allows you to play them in any key, change the speed, and mute any channel. Great to practice with!
