This is Never Enough, by The Cure. This appeared on a comp album they put out called Mixed Up, where they had a bunch of different artists re-imagine earlier work, and was an extended version of a new single. My roommate bought the album and I had this one track on heavy repeat back in the day. All of the current streaming versions are different than the one I remember—the one on the cassette was a little shorter and simpler, and I like that one best.
