There are, I suppose, as many ways of doing research on music as there are music researchers. I think what you have discovered, Praise, is the form or format that you would like to persue or peruse. That, to me is what makes this whole business of music so interesting. I have a couple areas that I'm interested in, and if I ever get the time, I hope to do a lot with it; I'm still in the collecting stage now. One of the things that interests me is the small changes (that sometimes lead to major changes) that are made in songs according to the REGION where they were collected.
For me, the exciting part is that someone like myself with absolutly no musical talent can still do more than just listen to music.
