Double-clicking an .mp3 file will start playing the file in the controller window, whereas single-clicking an .mp3 file will display the file's Song Title, Artist and Album information in the bottom area of the library window. You can edit the file's id3 tag information as long as the Lock File Info Editing option is unchecked in the Context Menu.
When you choose a file for playback from the controller window while the library is open, it will automatically be added to the temporary area. It can then conveniently be moved from there to a folder if desired. The temporary area is the list of files that is not contained within a folder. Please note that files in the temporary area will automatically be removed after the Audio File Library is closed.
MPEG Layer-3 encoded audio data embedded in audio file container formats such as eg AIFC or Microsoft RIFF/WAVE is supported for playback and will correspondingly be marked as .mp3 content in the file library window.
