Music Not Appearing in Groove on my Galaxy S6

[Windows Central Question]

I recently downloaded the Groove app on my Galaxy S6 and I can't get the music from my onedrive to appear on my phone. The music appears when I access onedrive through an internet browser, it appears when I use Groove on my Windows 10 PC, and it's all also saved in my OneDrive folder on my computer. How do I get it to show on my phone?
