Yeah this Master Writer program seems really powerful. I'm impressed with the near rhyme function. But there's three things it seems to lack. First, it can't rhyme phrases, such as "had a plan" "add the can". Second, it looks like there is plenty of Pop culture words, but it never showed a reference for slang. Third, it doesn't seem like it takes into account the multiple phonetic pronunciations of the same words. Depending on your accent, you can make some words rhyme that people with different accents can't make rhyme.
It would be cool if they'd incorporate those three things I mentioned above. Nevertheless, this does seem like a great tool.

Also, it doesn't look like it has double-rhyme, triple rhyme, quadruple rhyme, etc.... features.... It only finds rhymes for the last syllable of the word. Still, it can come in handy. But a good lyricist wouldn't rely on this much at all.
