The Pet Shop Boys had some great pop/dance tunes back in the day. Synths usually grate on me, but when the song is good (Suburbia, What Did I Do To Deserve This?, Domino Dancing), it doesn't matter. Still a major guilty pleasure though.
And even though I enjoy Van Morrison's "Into The Music," I can't help but see it as a guilty pleasure. Most of Van's music sounRAB like Phil Collins for Dylan fans.
