There is a word that I'm desperately trying to remember. I think it is used in the context of songwriting but it could be more general.
It describes the act of writing words to fit music, or to rhyme, rather than for the inherent meaning of the words.
For example, 'Don't take too much literal meaning from this song. The lyrics were written ________________.'
Sorry, I don't even know if it's a noun or an adjective. Does anyone have any idea?
