this is terrible!!!!!!!!! its way too fast and the singers are wwwwaaaaaaaayyyyyyyyy off pitch. Not even the real songs! This is rediculous!!!!!!!!! Worst Songs: 1.dynamite 2.only girl 3.teenage dream

One of the best albums I ever heard

The best sounds for a work out. Its upbeat and keeps me going, even when I want to quit!

Great mixing, excellent sound quality. These songs sound better than the originals. The tips/ booklet are great too.
