Hmmm.
The worst songs I've ever heard are:
1) Losing My Religion by REM
2) Nothing Compares to You by that Q-tip head, Sinead O'Connor
3) Tainted Love by Lindsey Buckingham
4) You Know The Love is True by Hall & Oates
They were lousy songs that should have been flushed at the very beginning. Rather, they were pushed onto the Top 40 and overplayed on every bubble-gum, commercial pop radio station in the country (or at least in Maryland).
