Try MusConv.com tool. I've tried this and this a great help for you.

Hello,

Please see [url]https://github.com/flarco/gonkey[/url]

It allows syncing of MediaMonkey to Google Music.
It evens allows syncing of play counts and ratings (2 ways).

It is still a work in progress, but it works!

Here's an unofficial solution for any kind of local playlist: [url]https://github.com/simon-weber/Google-Music-Playlist-Importer[/url]

It's a bit rough around the edges, but if your metadata matches it'll get the job done.

This is the add-on he's referencing:

Just install that and follow the directions he's posted.

Hello all,

I am new on the forums but a great fan of MM. I was curious to know if anyone knew how to import current MediaMonkey playlists into Google Music. Not just onto an Android phone, but actually transferring into the google music service so I can access my music both online and on my phone. I have done some research into this, and it seems I need the .m3u tags attached to my songs in order for this to work. The second comment by cmatte on this thread ([url]https://groups.google.com/a/googleproductforums.com/forum/#!category-topic/apps/the-cloud-lounge/walFUsmEVFA[/url]) seems to indicate that it is possible using a MM script, but I didn't exactly follow what he was saying.

All help would be greatly appreciated.

Thank you.
