Couple of days ago I heard a song Waldschrein by Equilibrium. Nothing special, but I am sure that the melody which they are are playing is a cover of some other famous song. I tried to google it but had no luck. Anyone recognizes it? I am sure I heard the original melody somewhere but can't recollect where, though I am sure it is something famous.
Really didn't want to post this question here, but I just can't get this melody out of my head :)
