Musicutils is a project mainly written in Python, it's free.
i needed something to help me upload select music to google music. this is it
############################ I have a lot of music. I also have a lot of hand crafted playlists which represent certain views of my music collection. Last time I checked google music only really interfaced with iTunes and couldn't import standard playlist file formats.
These "utils" are being built up around this one need, and will be expandeded as new needs arise. """""""""""""""""""""""""""""
