STill not so clear to me how these things work, but some songs should be put in the database, like these (each one has its thread postes some time ago)

Werin Daear (Welsh worker's song)
The Last of the Great Whales (posted by Joe Offer, I think, an ecologist song by Andy Barnes)
Chimes of Freedom (Bob Dylan)
A lot of stuff from Dubliners that's not yet in the database
Ordinary Man, by Christy Moore

Some famous Italian songs that were posted and I think they should be there (the database is mostly English-speaking but these are widely known):
Bandiera Rossa (maybe posted as "Avanti Popolo"): check for MY posting with full lyrics
Bella Ciao
