Today’s featured promo on MacUpdate offers Jaikoz Audio Tagger for US$15.95 (47% off, retail $30). “The Jaikoz Tagger allows you to organize, edit and correct thousands of songs with ease. It currently supports Mp4, M4p, Mp3 and Ogg Audio Formats. Jaikoz uses MusicBrainz, an online database of over 5 million songs. MusicBrainz is a community based database with contributions by over 200,000 people and its system of moderation ensures the data is extremely accurate. Many of these songs also have associated Acoustic Ids provided by MusicIP, allowing a song to be identified by the actual music, so it can do a match even if if you have no metadata.” Jaikoz Audio Tagger requires Mac OS X 10.4 or later.
