I renamed some songs in Tag&Rename but its change their name back after a few minutes of playing them through my media player. How I can keep the new names for these files?
Most likely you files were renamed by your media player. For Windows Media Player than you need to do this: go to Media Player main menu -> “Tools” -> “Options” -> “Media Library” -> “Automatic media information updates for files” -> “Rename and rearrange music using media information” check box – uncheck it if it checked. For iTunes: go to main menu -> “Edit” -> “Preferences” -> “Advanced” -> “Keep iTunes music folder organized” check box – uncheck it if it checked.
