I am a folklorist not a tech person...but have been doing web pages for a long time...

I like the large text file idea. One would put the keywords at the top rather than at the bottom on the same line as the title if possible. That is a song with the word love in the lyric would come up but also a love song would have the keyword love added to the title line. That way when you search for love song it would come up at the top of each instance.

Just open in your web browser and search.

The problem would be integrating the midi play files as they are now.
Not as advanced in html as I should be....but could it be possible to have a search cover both a central frame and border frames.

That is put the abcs in one file in a frame to the left put midi file links in one frame to the right and put the huge text file of all songs in the frame in the center.

If you could get one search button to search each file- left right and center the song would come up like a one armed bandit midi abc and lyrics and information all at once one after another.

These days computers can download much larger files quicker so the huge text file would be big but probably not prohibitive any more.

Just a thought.....probably ill informed because it is not all that informed at all but a thought none the less....
