I'm going to Hell

You know those times when your singing along to a song, like when it first comes on the radio, or you see it on TV, or your really drunk in a club or whatever, and you start to sing along, but there are no words yet? Like you just start impersonating the instruments. I don't know why we do it, but there are certain songs, which EVERYONE has to impersonate, even if you look a little scary and sound like a retard.

Below I've attempted to write down the way that I would sing five songs in particular. It's a pretty poor attempt, and I'm tone deaf, which may or may not help, but see how many you can guess. Click on the answers links for a BIG hint for each one. They're all well known, 3 of them are films, ones a TV show, and ones a random piece of music in a film, but you should be able to guess it, if you can't then... Do you live under a rock or something?

1. Nurna-Nurna-Nurr... Waaah Waaah Waaah... Nurna-Nurna-Nurr... Waaah Waaah Waaaaaaaa... [ANSWER]
2. Ree! Ree! Ree! Ree! Ree! Ree! Ree! Ree! Dun-Durrr, Dun-Durrr, Dun-Durrr... [ANSWER]
3. Dun... Dun Dun Dun... Dun Dun Dun... Dun Dun Durrrrrr... [ANSWER]
4. Dern Da-Da-Dern, Dum Dum Dern, Dern Da-Da-Dern, Derna-na-na Nern [ANSWER]
5. Dern Dern Dern Dum Da-Dern, Dum Da-Dern, Dirn Dirn Dirn Dum Da-Dern, Dum Da-Dern [ANSWER]

So let me know how many you got so I can either apologise profusely for my terrible effort, or laugh at your pitiful soundtrack knowledge. Either way I don't think that really makes me look all that great...
