Squeed

Squeed is a straightforward, efficient MP3, FLAC, AIFF, and M4A metadata (tag) editor with online database support.

Features Outputs clean tags: metadata that doesn't appear in the sidebar is not written to or kept in the file. Search on Discogs: search for an album or a track on the leading user-built online discography database and automatically populate metadata with that info, including cover art, all from within the app. Batch-process files: select several files at once and edit their tags or rename them in batches. Pattern renaming and tag extraction: batch-rename files with any combination of supported metadata or easily extract info from the filename. Preview audio inside the box: preview the currently selected audio files with Quick Look. Autocomplete tags: Squeed autocompletes as you type with metadata already present in other files. iTunes integration: add files to your library and get autocomplete suggestions from iTunes metadata as you type.
