As I make each document in WORD, I copy the title into EXCEL spreadsheet titled AA songlist to keep it at the top folder.

Now I can sort by title or type/genre (UK Trad, American folk, blues, seasonal, etc.) or artist/author.   I keep this index spreadsheet in the same folder as the songs. One day I may make each title in the spreadsheet a link to the actual document.

A number of my song sheets (have links to sound files or you tube videos, so melody is a mouse click away when I want to practise, but don't remember the tune).
