"Let's Practice! (Unused Mix) - Rhythm Heaven" is a high quality rip of the unused mix of "Let's Practice!" from Rhythm Heaven.
The melody in the beginning of the rip has been changed to the song "Popcorn" by Gershon Kingsley. Later at 0:09, the melody changes to "Axel F", and near the end of the rip we could hear dings from Crazy Frog.
- This is the first rip to feature Crazy Frog.
