Install MP3-Info CMM

MP3-Info is a clever companion that helps you organize your music collection. It is essentially a Plug-in for the Finder and iTunes.
MP3-Info displays valuable information about audio files, such as their duration, the bitrate, important MP3-Tags, such as the artist, the title of the song, lyrics, cover art, and some more.

That saves you a lot of time managing your song collection. It also shows these information for AAC files created by iTunes, and WAV, and AIFF files.
