I downloaded a song by searching for something like medieval chant and I found a song, mistitled as it turns out, and now I'm trying to find out who it's by. I've asked at a Gaelic forum, here

Edit: song here; Be warned, every time I try to play it, my browser shuts down. Maybe downloading it is OK.
The gaelic forum thinks they are saying this in one part:
Aréir id Deo
Chuaigh mé lei ar strae
Tar súil sí romham
Suas den tobar tú (or tobann)

Great song at least.

Hi,
I can't open this file, it doesn't seem to be a music file but a text file. I am Irish so might have heard of it.

Do you know how I can change it from automatically opening in windows media player (which won't play it for me "codecs needed or something")? I still can't access it to hear it.

Should be able to download it, right click on it and select whatever player you want to open it with. Or are you not able to download it?
