I’ve tried about 8 programs that manage mp3 files and create/modify etc. play lists. Hands down, this is the best of those that I examined. Tag editing is a breeze, and changes carry over to the folder where the mp3’s are stored. For example, with a couple of key strokes, I changed all first letters of artists and songs to capitals. Saves time at this stage as well as when you burn, e.g., in Roxio. Play lists can be exported to Excel for easy printing, in a variety of formats.
