Transfer music playlists to the Nighthawk X10

I’m considering getting this router, partially for the Plex Server. My primary purpose would be to access my music library remotely. I see from the support article that the server can’t support a Premium Music Library. That limits the ability to create playlists based on genre or mood. So if I create those playlists on my desktop Plex Server, can I transfer them to the X10? That would allow me to have my PC shutdown while traveling, but still access the playlists I create on it.

If that’s not possible, are there any other ways to assemble a playlist for, as an example, all the 60s Rock scattered through the library?
