Super Mario 64 & Mario Kart DS SoundTrack Error Message

Whenever I Try to Download any of the Super Mario 64 SoundTrack or Mario Kart DS’s "15_peach_gardens.mp3"–and possibly all of the Mario Kart DS Music that comes after it–from GH onto my Windows Media Player, I keep getting this Error Message:

"Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."

I’d like to Request for this Problem to be Fixed so the Music is Available for Listening and Downloading.
