I don't really do favourite songs of all time. I like loads of songs and I tend to have a favourite song of the moment and it changes every few weeks lol. Right now it's Dizzee Rascal's Dance Wiv Me.
I also love Cyndi Lauper, Coldplay, Michael Jackson, Tenacious D, Disturbed, Nickelback, Sean Kingston, Stone Sour, Foo Fighters, Linkin Park, Basshunter, Nirvana, Candlebox... the list is pretty much endless lol
