Papa Roach first got my attention with their song Last Resort and officially hooked me with Between Angels and Insects. Despite the stupid band name and the lead singer who couldn't sing, I still found myself enjoying the catchy guitar work and meaningful lyrics. After some early success, they couldn't have followed the path of so many other young bands and partied until they had spent all of their money and wound up in rehab, then putting out a mediocre album or two to try to capitalize on their previous success. Instead, fast forward 9 years and they have worked hard to refine their craft. Jacoby Shaddix has even learned to carry a tune and does an admirable job on many of the songs.
Long story short, Metamorphosis has 3 good songs - Hollywood Whore, I Almost Told You That I Loved You, and Lifeline - along with a handful of ok songs. Not a memorable album, but they are showing progress as musicians, and it was worth the $8.99 to download the whole thing from Amazon.
