I use Rhythmbox for sorting opensource audio I have collected. Now...I would like to copy 200 audio and add them to my micro sd for my headphones, so I can listen to music on the go.

I got all the audio tagged by genre. How would I copy all the files by genre? I know "audio tag tool" can create playlists, but I am not exactly sure how that works. I do not wish to move the files from their current positions and I very muchly do not wish to copy all genres with 10K+ files.
