Yes, I agree, we shouldn't get too hung up on finding rhymes for 'orange'. I've never yet felt the need to use the word 'orange' at the end of a line in a lyric or poem!

By 'good' rhyming words, I meant words that are themselves useful for poems/lyrics.

As a negative example, 'anti-inflammatory', having a very specific meaning and being difficult to rhyme, is a pretty useless rhyming word, unless used for comic effect in a lighthearted poem.

Whereas 'again' is a versatile word which rhymes with many other common - and also versatile - words.
