Naemanson, sometimes you need to be revved up pretty good for them to start. For me, writing anything can get the song thing started too.For you, if the tunes do come, I would suggest the tape recorder. Keep a little cheap one handy.
As far as words-- well heck, send me an e-mail describing what you'd like to write about, and let's see if we can pop a song loose.
