Ex Input:
I am an AVID music lover. I'm a musician, producer, songwriter, and record producer. This is simply not worth my time. Do yourself both justice by either checking out this band's earlier work like their self-titled album, or even the live cd/ep. It does sound better in that they got to be themselves rather than try too hard, just good old rock music.

Ex Output:

Bad review
