You've bought the mp3 backing track - great! The only trouble is that it is too fast for you at the moment (or maybe even too slow...). No problem! Here are some super easy ways to put a track at a more manageable speed:

IPHONE, IPAD, IPOD, ANYTHING I-RELATED

Get this app!
Tempo SlowMo - BPM Slow Downer
It's free and it's great! It will open any song in your music library or you can open a piece directly from your email (just hold your finger down on the attachment). Then you can adjust the speed by 1% increments (slower or faster).

ANDROID

Get this app!
Audioshift
It's free and it does the same thing as Temp SlowMo.

ON A PC?

Try Slow Mp3.

Each track is presented in two formats - a "performance" track and a "practice" track with clicks throughout.
