Oh I don't know. It adds a slightly fake element to rhymes when you just use sites like 'rhymezone' to get words to rhyme with. I guess it's a personal choice, but nah, that isn't for me.
I use a thesaurus sometimes, and a dictionary to check spelling and that words exist, but that's it. If you need a program to tell you what words to rhyme with, then you can't be much of a lyricist, and are really only f*cking with the people that are true to the game. Thanks for killing the music. Too much crap out there nowadays is manufactured and created by people trying to be people that they are not. We don't need more.
