Hello,
I do not know whether I mentioned it before but sometimes there is a bug in the portal's engine.
I made some title (did not know it was already used by somebody), so I changed it and added "!!".
But the old name still is present as a link.
Hence, having a song http://chipmusic.org/mister+beep/music/bit-by-bit , I am still getting messages about... another song, haha. 
About this one - http://chipmusic.org/music/view/bit-by-bit
Maybe it could be repaired somehow, I don't know.
Regards.
