How do I get Google Play to access music that I synced to my Samsung 8+ using Windows Media Player?

[Android Central Question]

I synced a playlist from Windows Media Player to my Samsung 8+. The music is on my phone under Phone > Music but does not show up in Google Play. I can play the songs individually from My Files > Audio.

You need to upload the music to Google Play Music.
You can do this directly on your browser in Windows (or Mac or Linux). Open https://play.google.com/music > menu > Upload music.
You might be asked to install Google Play Music Manager to complete the process.
To the best of my knowledge, you can't do this from your phone, only from a desktop or laptop.
