I’ve always found uploading my music to Google Play Music a pain using their tools to be a pain. Luckily you can do it via your CLI!
pip3 install docopt gmusicapi-wrapper
Download the gmusicapi script to upload our music (supports .mp3, .flac, .m4a, .ogg):
Run the gmupload script:
For even easier use (access the script from anywhere):
mv gmupload.py /usr/local/bin/gmupload
Please note, on the first time running this you will need to follow the link provided by the script to insert your authentication key into terminal.
For specific usage of the script have a look at the documentation here
