Hi there,
Just to point out that a field or space should be available to put the real authors of the song. Or at least an incentive to do so.
Most authors will not mind that their lyrics are shown all over the place except that it is rarely mentioned who wrote them and people associate the lyrics to the singer or artist. And not that many artists write their songs. Not that the singers are all complete illiterates but ... well some of them are.
Various tools are available for that (that could be linked somewhere to help for that).

and so on...
While it is an additional task, it is a question of putting the credits where the credits are due.
Cheers
