The songs that annoy me most are those that have really forced lines/rhymes in, and those do indeed tend to be contemporary because the folk process generally digests and evacuates the bad bits.

I genuinely believe that the worst line of the lot is 'Judge's fine and private daughter' in Palaces of Gold. Noone would ever use that as a phrase. There again I've never heard anyone describe Mr Logie Baird's invention as a Telly V - but it didn't stop Ron Angel using it in his song about the decline of Christmas.
