rgbpm  assumes  that  each folder contains one music album, with all audio tracks in that folder being of
       the same file type.

       rgbpm will traverse from the given folder  (or  folders)  to  all  sub-folders,  adding  the  recommended
       ReplayGain 2.0 track and album tags to supported audio files.

       If 'loudgain' is installed, rgbpm supports the following file types:
         - FLAC (.flac)
         - Ogg (.ogg, .oga, .spx, .opus)
         - MP2 (.mp2)
         - MP3 (.mp3)
         - MP4 (.mp4, .m4a)
         - ASF/WMA (.asf, .wma)
         - WavPack (.wv)
         - APE (.ape)
         - WAV (.wav)
         - AIFF (.aiff, .aif).

       If  'bpm-calc' is installed, rgbpm will use it to calculate beats per minute, then tag the following file
       types:
         - MP2 (.mp2)
         - MP3 (.mp3)
         - FLAC (.flac).
