Maroon 5 has always been a sanitary wipe of a rock band, with a sound that radiates outward from the singing voice of frontman Adam Levine - an earnest, tangy-smooth falsetto that has a mysterious ability to clean up after itself. And that must be why this band remains so durable, right? Because its music is so repeatable? I think so. To hear a Maroon 5 song - any Maroon 5 song - is to feel your brain being wiped clean of the experience as it's happening.
