I have tentative playlists for my Dual Disc Debacle cds. I'm doing an Abecedarium, with some license because I figure Magpies aren't too persnickety about their alphabets and because 26 songs isn't enough to fill up two cds. Test discs are burned for the MO to try out in the car tomorrow. I expect a ... moderate ... reaction because I know that he really hates some of my music, but it's quite a mixed bag (I defy you to put together a single-genre abecedarium (by artist, not by song) from your existing collection) so I think there's something for everyone, even a headbanger like him ;-) and while there are a couple of rough transitions, as a whole I think it works.
The next task is the artwork. Yippee!!
