can't find my playlists I made once I plug phone into computer

I have downloaded all my music to my Droid Eris FROM my Droid Eris using the Tunee App and from these songs, I have made different playlists. I want to take one of the playlists I've made on my phone, and burn it to a CD. When I plug my phone in to the computer, I open the Music folder, and it simply has a list of the 167 songs that I have downloaded. There is no folder specifiying playlists. Is there anyway I can transfer individual playlists to the computer? Or do I need to go through my whole list of songs and just sepereate them into playlists again?
