HymnWiki

HymnWiki is a site dedicated to hymns, children's songs (at least ones associated with churches and religion), religious anthems, church music, other music commonly grouped with hymns, and compilations of such, with a large focus on the music of the Church of Jesus Christ of Latter-day Saints—though it is meant for all church hymns, regardless of affiliation. HymnWiki began in April of 2007.
