Not sure I can pick a favourite song of all time. I'd probably have to say something unimaginative like Comfortably Numb (live 8 version), Wish You Were Here or Shine On You Crazy Diamond (Delicate Sound Of Thunder version).

Wish I could say some litte known Floyd song and not be as predicible but any mood I've always got time for any of the above.

None Floyd theres a few songs that are up there like Dethrone Tyranny by Gamma Ray or Victorias Secret by Sonata Arctica.
