Cover art for Burnin' For You lyrics by Blue Öyster Cult

And the correct line is "time to play B Sides", the things you used to have in the vinyl age. Kids, ask yer parents...

Buck Dharma now mimes the action of flipping a record when he sings that line, just to make sure.

@RedKing As printed, I believe you are right. However, it could also mean time to play besides, as in devil's advocate (playing with the "devil" theme here). But that would be implied, an extension of what is the beauty of BOC's writing style - they intentionally load their lyrics with entendre, ambiguity, swirls of multiple trains of thought (this one has at least two ideas swirled together) leaving doors wide open to interpretation and imagination.
