"Weird Al" Yankovic knows a good song when he hears one — four decades' worth of spot-on parodies can attest to that. But the singer-accordionist, who's gearing up for a summer tour in support of 2014's hit Mandatory Fun LP, also has an ear for the offbeat, as this playlist demonstrates. "I want to stress that these are not bad songs," Yankovic told Rolling Stone of his selections. "I personally really like all of them. All I'm saying is, this is a sampling of tunes that most people wouldn't particularly appreciate hearing through their bedroom wall at two o'clock in the morning."
