Reasons for Better Rhyme

It gets very tiring to my ears to hear contemporary/popular music rhyme the same words over and over like, say: go, know, no, and so; or knew, true, and you. This rhyming abuse is why Thesauri exist in many formats, especially in Word so plagiarizers can remodel what they cut and pasted; if those sources are too complicated than consult rhyming dictionaries so my ears get more interesting rhymes like lizard and slizzard.
