Writing Playlists to thumb drives for vehicle use

Hey guys and gals. What would be the easiest way to copy the contents of a LMS playlist to a thumb drive? I have close to 90K tracks in my music library and my RAM truck "system" max's out at 20K tracks. I thought maybe I could make some playlists with LMS and copy the content to a thumb drive? Each thumbdrive would be a different playlist. It would be a neat LMS plugin! Only way I can think of is using a music app such as Media Monkey which accepts M3U files and give the app the same mount point as LMS uses for the music library.

Thought?

Have a great weekend
