Personally, I'm unconcerned about the lyrics; I simply thought you wanted to make your MIDIs available. There's a good chance most of the texts will already be available online, through sites like Google Books, Internet Archive and Hymnary.org. If the music is good but the lyrics are uninspired, perhaps someone will match a few of the tunes to more deserving poetry (like drinking songs—considering the many hymn tunes usurped from folk song, a little payback is not amiss).
