There are many sensible ways to take advantage of a costarring role on the most critically adored TV show in recent memory. Bafflingly, Jamie-Lynn ”Meadow Soprano” Sigler has ignored them all in favor of an attempted career as a teen-pop star. Can she sing? Sure, well enough. But Cry Baby, the first single from her upcoming Oct. 16 album is astonishingly unoriginal, shamelessly stealing from ‘N Sync’s ”Bye Bye Bye” and J. Lo’s ”Love Don’t Cost a Thing.” Still, a better career move than getting arrested for robbery.
