Thyme, Rhyme

Pretty close for my calculations.

Anyway Rhyme is the punctuation of poetry and lyrics. The music has echoes and repeats, and choruses to do that anyway. There is a whle sub-genre called tone poems. Rhyme is just one more bullet and you can slay them in other ways. No sense in filling them with lead if you have already deaded them.

I personally like the occasional "rhyme refused", it has a certain humour if the word they all expect is rude and the first sounds let them think it will be that word, not to be overused though.
