How can I transfer a playlist straight to my PC?

The key is that my music files are all over the place in separate folder in my phone. It would be too time consuming to sift through every folder and pull out the individual song files that are in my playlist, not to mention some of the files are weirdly named so I'd end up missing some. I'm trying to move just the songs that are in said playlist so I can burn them to a CD. The music app on my LGG4 let me export the playlist into an ".m4u" file but I'm not sure what this does or if it even helps. Any guidance? Thanks in advance.
