Each week, we'll be featuring the worst songs from each year this decade. We'll be counting down the absolute worst songs to come out each year from 2000 to 2009, and we'll be bringing back all of the songs you wish you'd forgotten. These are the songs that people just can't seem to believe exist, because they're just so terrible. There is a good mixture of guilty pleasures (the awfully funny) and complete crapfests (the awful with no merit). At the end of the 10 weeks, you'll have an opportunity to vote on the worst song of the decade.

2004 had a lot of bad music, but one family took up about 1/3 of this list with their awful voices. And the rest of the list is populated by some odd stuff you couldn't invent again if you tried. So what made you want to slit your wrists in 2004? These songs:

10. Five for Fighting – 100 Years

The song’s concept is stupid, but that isn’t really why it’s on this list. This guy’s voice is so fucking annoying. Who could listen to this without shooting themselves in the face? Do they torture war criminals with this song on replay? Do dogs in heat run into the room when it’s played? Whatever the song’s use, it shouldn’t ever be considered decent music.
