Pro Tips for a Clean Music Library
- Square art wins: use 500×500 to 3000×3000 px JPG/PNG covers — players crop anything else.
- Consistent artists: pick one spelling ("DJ Alok" vs "Dj Alok") or playlists split into duplicates.
- Track numbers as 3/12: including the total helps some players sort multi-CD albums correctly.
- Old cache: if a player still shows old tags, it cached metadata — remove/re-add the file or refresh its library.
- Not an MP3? Convert M4A/FLAC/WAV to MP3 first with our Audio Converter, tag it here, then trim intros with the Audio Cutter.
- The download keeps original audio bitrate — check it with any player's file info to confirm.
