Parents need to know that there's some gleeful sexual innuendo (the song "Inside of You" speaks for itself) in the midst of a whole lot of rock & roll clichés.
If you are a hoobastank fan it still wouldn't hurt to skip this album. While most of the songs are lyrically fine (although not musically so) "Inside of You" is enough to earn the cd a placement in the trash can. All the song is about is promiscuous sex. It is explicit in doing so and does not present any kind of loving relationship coming first.
