First up I'll openly admit that I don't keep up with music so I'm limited to what I know was released this year. My personal favourites are...
Kano - Nite Nite
Fall Out Boy - Sugar, We're Going Down
The Killers - Mr. Brightside (released late 2004, though, I think)
Lifehouse - You and Me
I had to check a few lists for those songs. I didn't recognise a lot of the songs shown. :(
