I've never known WinAmp to be exclusive to any particular file type; I've essentially used it to play .wav and .mp3 files ... all easily accessibly via Windows Media Player as well. If you're WinAmp is failing, you may simply choose to save the song file to your desktop --- then open it with Windows Media Player.
On a side note, and to my knowledte, WinAmp's always been free. WinAmp may not be working if other player types are currently open.
