Something that drove me crazy when I first started to visit the 'cat - lyrics would be posted and requests for chords would flood in - but everyone assumed you knew the tune!!!!

and yes - by the time you consider variants in lyrics, chords, etc - each DT entry would either have to be multiplied several times or so annotated that they would become incomprehensible.

But I also get fascinated by people discussing the difference in chords for a particular song and why they use this that or the other.
