a little late once more, but let me try to add my 2cents to this thread.
As it has been mentioned, we've had a similar discussion some time ago, leading to what we ended up calling the "lyric library"-idea, which I admittedly didn't follow up too much, seeing that I have ... yeah, you now.
hat I did do is pass on the idea of the "lyric library" to our friends at Leipzig media university, and there was a student who wrote a master-project-paper on the topic of integrating such a feature on wikiloops. I actualy visited Leipzig a few weeks ago to attend the final presentation of that student, which was quite a nice experience.
Now, that has not really brought us anywhere nearer to having the ideal solution at hand so far, but when discussing the idea,
the one aspect that seemed most problematic (and which we hadn't thought of in our initial discussion here) is the following one:
The idea to host some kind of lyric library where people can share written lyrics and hope that someone will use them in a wikiloops collaboration is nice and well,
but to find a track which will match the verse / chorus structure of the written lyrics will be very difficult. Singers might end up realizing the track was missing the repetition needed for the final verse, or the chorus being just four bars longer than needed, to find the ideal match would be a very lucky moment. The only way to increase the chance of getting to actually sing some of those lyrics would be to take the creative freedom to change the offered lyrics in some way to let them match a song, but then the lyrics in their original form might be turned into something which the original author would not confirm of.
Just think you had written a song that praises the government for three verses, which turns out to be totally ironic in verse four... now comes singer X and uses only the first three verses... ouch!
What has been considered by some of you is a little different from the idea of a "stand-alone" lyrics collection - if you are thinking to provide "unsung" lyrics along with a track (which definetly has a matching structure, then), the major fault of the lyrics library idea would not apply, while the use of those lyrics would be less "free", but rather attached to using them on the track the lyric author chose.
To me, that would be less of a "library", but might be better named as "un-sung songs section", hope you understand the distinction I am trying to make here :)
Similar to what I said last time, I'd like to encourage you to experiment with the idea before I rush to developing.
As things are right now, you have some options how to go about:
If you are the author of the track to use for your lyrics, you might as well add them to the description field for now.
To add them in the "official" lyrics field, you would have to:
1st change your upload to "vocals"->save
2nd re visit the edit page, enter the lyrics into the now showing lyrics field, save
3rd re visit the edit page, change instrument back from vocals to what you really played, save.
If you are not the author of the music but have written a lyric for a particular song, I'd suggest you post these to the forum, ideally with some common "tag" to spot such threads, p.e. "unsung song: Benny the Beaver". Then, write a comment below the track you chose with a link to that forum thread and see what happens.
Sorry for the extensive morning read, hope that's putting things in perspective a bit ;)
