Hallo,
Hopefully this hasn't been posted before, and isn't against any of the TFP's rules (if it is mods, you know what to do).
Anyways, this song is a cover of the poptastic Toxic by Britney Spears. Fortunately, its one of those covers thats a vast improvement over the original IMHO.
The cover'er is Tristan Prettyman who has a voice as smooth as silk.
Enjoy fellow tfp'ers
