We’ve talked about one-hit wonders before. I like to think of Maroon 5 as a one-album wonder. Their debut album, Songs About Jane, was a terrific pop-rock outing. However, everything they’ve done since has been banal ultra-pop. The promise of Maroon 5’s first album has given way to a bunch of boring songs — usually in Adam Levine’s falsetto — that all sound the same. To be totally honest, I think the success of Maroon 5 rests largely in Levine’s appeal as eye candy. After all, we all saw the reaction to the band’s Super Bowl halftime performance.
