Let’s cheer things up with a little ’90s power pop, courtesy of one of its top practitioners. “I’ve Been Waiting” was the second single from Sweet’s 1991 album “Girlfriend,” declared the top power pop album of the ’90s by the AV Club. He wrote the songs in the wake of a divorce and the commercial failure of his first two albums, and judging by the video, his rebound girlfriend was the anime character Lum. He even has a tattoo of her. The lead guitar on the track is by Richard Lloyd of Television fame.
