I completely messed up when syncing my music files to my htc one x and as a result I have no idea which songs I have and which songs have been duplicated, so I decided to delete every single song and just re-sync all of my songs, but I cant delete multiple songs and have to delete them one by one, which is very very irritating and time costly as I have over 400 songs. I have tried using various 'file manager' apps and they seem to delete the file content but when I go to my music it all still shows up, just nothing plays. Is there any way in which I can delete all of my songs in one go ? I would be very grateful if anyone can help me with this matter. Thanks
