Batch music tag editor for MP3

Fix song titles, artists, albums, track numbers, and cover art directly on your phone. Your music and edits stay on your device. Pick a track or a selected batch, review the changes, and save when you are ready. Before and after each in-place edit, the app checks the audio portion of the file and shows whether it stayed unchanged. When Android asks permission to edit indexed music, the app groups eligible files into one system request for that save and tells you how many it covers. Files in a folder you chose use that folder access. If you resume a paused batch, Android may ask again for the remaining files. Scan up to 5,000 supported tracks from Android's music index, or choose a folder. Folder scans cover supported files directly inside that folder, not nested folders. DRM, cloud-only, unindexed, or inaccessible files may not appear. Nothing is written until you choose the tracks and confirm the save. Supported candidates include MP3, FLAC, M4A, OGG, and WAV files that pass the app's preservation checks. File structure and provider behavior still determine whether a file can be read or written. If a check fails, the app refuses the file. Edit title, artist, album artist, album, composer, genre, year, track number, disc number, comment, and cover art. Only the fields you select are changed. Supported tag fields you do not change are preserved. If the app cannot verify a safe edit, it refuses the file instead. You can also inspect codec, bit rate, sample rate, channels, bit depth, and measured tag and audio byte counts. After a save, the app reads the files again and shows the saved values. Preview selected batch changes before saving. Find and replace, change case, number tracks, copy one field into another, read artist, title, and track number from a filename template, or write a copy named from its tags. Copies leave the source file in place. Save a batch setup as a preset. If a long batch stops, it keeps its place. Reopen the app and choose Finish the rest; already-saved files are not planned again. If a file cannot be saved, the app names it and explains why. The result separates saved, paused, and refused items. Undo can restore the latest in-place batch from a private on-device backup. It skips files that changed afterward, are missing, or cannot pass the current safety checks. Undo does not delete copies the app created or their source files.
