On their infectious second CD, Gym Class Heroes add club hooks to their usual rock/hip-hop blend (the girl-chasing ode "Cookie Jar"), and frontman Travis McCoy even talks "getting married" to squeeze Katy Perry on the gushy "Kissing Ears." (Fueled by Ramen)

This Texas girl has finally found a home on the range. After a seven-album string of mediocre pop, Jessica Simpson successfully connects with her country roots for her first CD in the genre. She duets with Dolly Parton on the sweet title track, confronts an old boyfriend on the ballad "When I Loved You Like That" (are you listening, John Mayer?) and croons about beau Tony Romo on the romantic ditty "You're My Sunday." (Epic/Columbia Nashville)

NKOTB's comeback disc (their first since 1994) offers the right stuff on a few melodic pleasers including the breezy single "Summertime," but the guys sound caught in a midlife crisis on dull fare such as "Dirty Dancing." (Interscope)
