Journey's signature 1981 top 10 power ballad "Don't Stop Believin' " has endured at least nine pop culture lives—most recently when Tony Soprano played it on a diner jukebox during the "Sopranos" series finale—as the final scene cut to black with the words, "don't stop." Exposure hurled the track to the top of iTunes' download chart, prompting Legacy/Columbia to reservice it to radio. Two years ago, "Believin' " also returned to public favor as the unofficial theme of World Series baseball champs Chicago White Sox, then aired in episodes of MTV's "Laguna Beach" and Fox's "Family Guy" the same week, propelling it to No. 2 on iTunes. In our modern singles paradigm, the expression sure holds true: "Rock'n'roll will never die." —Chuck Taylor
