Well the Tad Williams ones do go up and down in pace, so you may have easily drifted away.

I felt the same way about the filk songs and then I got some off a friend and now I'll admit to a certain fondness for them.

I've put together a bunch of songs which can be found through the link at my journal.

(As this is my first time trying to do this - bear with me) The full description of songs and the file can be found here (http://maire-x.livejournal.com)
