I tend to agree with Nite.....there comes a point when the skill of telling a story using rhyme and meter is lost because a word processor churns out meaningless garbage that rhymes and syllable counts.
I do not think that such "tools" will ever compensate for a good education and a working knowledge of language, songwriting and music production but it might helps peed up the process.
I was in the studio only yesterday and the guys were discussing different plugins that they use for mastering and editing etc. One guy liked a certain program whilst another used different software........each had its pros and cons. Each served a purpose.
The concensus was that at the end of the day results come down to "ears and experience".....the tools of preference just help you get there faster.

OK Here is a profound statement for Ott based on the chicken egg scenario. Why did the duck cross the road?.....cause it was the chickens day off.
Think about it.......
