[porg]

Environment

• macOS 11.4
• mp3splt 2.6.2_1
• Installed via https://brew.sh

Reproduction

Download the audio track of a DJ mix published as a Youtube video

youtube-dl -o mix-file.mp3 -x --audio-format mp3 --prefer-ffmpeg URL

Parse video description for a tracklist and generate a CUE file from it

youtube-cue URL sheet-file.cue

Split the mixfile into individual tracks according to the CUE sheet

• And name the album folder and the track files by this scheme:
• Album Title/TrackNr Performer or else Artist - Song Title

mp3splt -o "@b/@N @A - @t" -c my-sheet-file.cue my-mix-file.mp3

Expected Result and Actual Result

• ✅ The folder name and the file names are properly created according to the tag scheme.
• ✅ Per each track (MP3 file) the ID3 tags are set accordingly to the maximum information contained in the CUE sheet:
  • ✅ Track artist (=PERFORMER stated per each TRACK entry in the CUE file)
  • ✅ Song title (=TITLE stated per each TRACK entry in the CUE file)
  • ✅ Track number (=Nr stated next each TRACK entry in the CUE file)
  • ❌ of total amount of tracks
    • The manual mentions Total tracknumber is not yet supported
    • If I may ask: Where's the difficulty? Reading/interpreting or writing the metadata?
    • In case if it's interpretation: I'd be absolutely satisified if interpretation is plain and simple: Simply choose the highest encountered tracknumber as the total number.
  • ❌ Album artist (=PERFORMER stated in the first lines of the CUE file), the DJ of the DJ mix.
  • ❌ Album title (=TITLE stated in the first lines of the CUE file), the DJ mix name.
    • Why did the properly parsed info not make it into the tag of the ID3 metadata?
    • The folder was properly created by @b.
