Train, "If It's Love"

Train revived its career this year with "Hey, Soul Sister," its biggest hit to date and one of the catchier songs of 2010. The trio has more where that came from, though. On follow-up single "If It's Love," a rhythmic guitar vamp opens in the band's signature cheerful fashion as frontman Pat Monahan's tenor hits glorious high notes on lines like, "I'm not in it to win it/I'm in it for you." Gregg Wattenberg (Goo Goo Dolls, Daughtry) and Martin Terefe (KT Tunstall, Jason Mraz)--who co-produced "Hey, Soul Sister"--know how to build appealing instrumentation and a standout vocal, and their winning formula works again here. Train continues to prove itself adept at uplifting rock tunes that resonate with all types of listeners. --Michael Menachem
