Hah, finally got it - IT WAS YOU ALL THE TIME!!
Last April the 2nd. when I woke up after a horrible nightmare and opened my computer with all the basic favorite websites and started to make breakfast. Then suddenly I heard an orc voice saying "I saw your nightmares and they were d'elicious!" In such a way that I had to come out of my kitchen and stare around my living room and come to my computer and check what the hell was happening. I suspected MMO first but I tried to close it and re-open it but nothing happened.
Now this morning I got up the same way but I heard this familiar type of music from WoW so I got a chance now just to close this one window and boojaah, it was MMO-Champion! But then I noticed that now the music was gone and can't play it again
Thanks for the great prank last april fool even tho it came a day late!
ps. You could do a miniplayer that starts to play wow music every time we login, right?
