DepenRAB what you mean by "great".
I personally hate it because a) it makes your songs extremely predictable lyrically-wise, and b) usually, rhyming is only used in a very basic level, as if written for a junior high presentation.
Nonetheless, I can appreciate a good rhyming pattern if it's well made, but I try to stay away from it because it usually makes my writing weird and common place.
I'll make a write-up on rhyming, anyway. But that will be tomorrow.
