Wow, can't believe I missed this topic. Um, let's see:
Steve Miller Band (can you say no talent? Anyone here has more talent than him.)
Fleetwood Mac (for the most part. Landslide and Silver Spring (or springs), were good.)
Just about any modern rap (I think I like some, but I'm not sure.)
Mariah Carey (oh God, the woman can't sing to save her life.)
Shakira (Speaking of no talent.)
Sort of Gwen Stefani (I'm basing that on one song, but Hollaback Girl has to be one of the top 5 poorest/stupidest songs ever written).
