Need help identifying song
 

This is a very memorable trance? song I think from the 90's or early 2000s, but I just can't remember its name.

I managed to sort of recreate part of the tune on a virtual piano (the rythm is a bit off, but the notes are right) . Here is the recording: (~170kb) mediafire.com/download.php?fu50wemf2dkcmyc

Would really appreciate it if someone could help identify the track.. Thanks a lot!
