Okay,I have had this Windows Media Player forever and this has never happened before. I went on Windows Media Player like I do whenever I go on the computer. (Listen to music blah blah) Then I of course double clicked my favorite song ( American Idiot by Green Day) and it sounded strange. The music was playing but the singing was so quite that you could barely hear it. Then, I tried a different song, accept this time, the track sounded weird too, and the singing sounded slightly techno.

Please help me, I can't live without music.
