HoH #7 - Backwards Songs

Vul, Penguin, Leoin and Smarties will be playing in this HoH challenge.
Ninja, as the outgoing HoH will not, but can join along for the fun if wanted.

Here are the links to 15 songs that have been reversed, all you have to do is tell me the name of the original song (not the backwards one... I mean you could spell it backwards if you'd like, but you'd be wrong XD) and tell me the name of the artist who made it. Listen closely from start to finish because most of it is utter gibberish but there are a few key recognisable voices and sounds for each of the 15 songs.

You will get a point for the correct name of the song, as well as the correct artist.

30 points total, highest scorer will become the new HoH :)

Rules:

No cheating!
No Re-reversing,

No outside help!

You may, however, use the internet to find the name of the artist if you already have worked out the song but you may NOT use it for anything else.
