Motorola Droid Turbo :: How To Find MP3 Transferred Into Music Folder Via Computer

I have a droid turbo. When i throw my music into my music folder that appears after plugging my phone into the computer, i cant find it on my phone. I will either put MP3s directly into the "music" folder, or i will create another folder within the music player, name it after the band or album, and then put the mp3s into that newly created folder. Then upon rebooting my phone, the music doesn't appear in the music player application. Though if i do put music into my "downloads" folder i am able to find it, though with this method i am unable to organize the music at all.
