The Best of Both Worlds

”Turn your clock back,” Sammy Hagar shrieks, appropriately, on ”It’s About Time,” the sturdy new stomper that kicks off an expansive hits set from the originators of squealing pop-metal. Though the two-disc The Best of Both Worlds reprises much of the band’s 1996 best-of CD, it does add essentials like the harmony-soaked ”Jamie’s Crying” and the libidinous ”Poundcake.” But it’s also padded with torpid Van Hagar ballads (”Love Walks In”) and tacky Roth-era covers (”Dancing in the Streets”).
