I use to use ieatbrainz but have always had my jaikoz because it is great for large libraries (especially the lyrics feature!)
What I loved about ieatbrainz was that I could search through my itunes library and select playlists to autocorrect within ieatbrainz… there isnt that option in jaikoz and it is really hindering my use… it is too much trouble to manually find each song through the folders (i have itunes organize my folders)
