I have my phone running on 2.1 os and I downloaded some app from the market for karaoke. But my phone went really slow and i uninstalled this app. However, all my music tracks are now playing like songs on a karaoke where the vocals are largely gone. However, if i connect my phone to the computer and play songs, they are all just fine, which suggests that the tracks are all fine. Its just that something in the music player and the media player has changed. please help me asap coz I can't really work much, without my earphones plugged in.
