A.B. Quintanilla keeps up his frenetic pace with this collection of duets. It's slightly creepy to hear Selena on her bro's 2005 album, but the post-mortem collaborations should make fans really happy. "Don't Cry Mama" picks up where Tupac's "Dear Mama" leaves off and who could take issue with "No Tengo Dinero"? "Together" should get all up in your something-or-other.
