Good and not very innapropriate just sorta bad themed. It was like my favorite song in 4th grade. I really like it. Not so much now though, but its still on my itouch.
Actually, I think this song doesn't have a good or bad message. Just a sad one. Depending on how it's interpreted, it can be a song about how this guy has a problem of not being a good bf, and he's warning girls "I'm not the perfect person".
DO NOT LET 11 AND UNDER STUDENTS SING IT IN K-5 SCHOOLS!
Well, My 8- and 11-year-old friends will sing it in K-6 schools. It's like Elementary School. Your child needs to be in Senior High School to sing it and Junior High School without copying the bad behavior.
