In general, Leawo Music Recorder for Mac would automatically download and add music tags to recordings, including artist, song name, album artwork, album, etc. But if you’re not satisfied with the results, or the program fails to recognize the recorded music files, you can edit them manually.
Step 1. Choose the recorded music with the tags you want to edit in the Library or PlayList and right-click on it. Then choose “Edit Music Tags” in the pop-up menu.
Step 2. On the "Music Tags Edit" panel, edit the music tags including artist, song name, album artwork, album, etc. Finally, click OK to save your modification.
