"How do you all feel about perfect rhymes? ...
Also how do you feel about the use of emphasis on the wrong "syl-ah-ble"
such as rhyming "see" with "ener-gy"? "

This echoes some of the Craft that I alluded to earlier. Rhyme, prosody, rhythm, pitch interval & progression... all the myriad details that can be examined when dissecting a song. There are Rules of what is Good (such as perfect rhymes, words flowing as normal speach). I think it's safe to say that any "rules" of the craft of songwriting can (should?) be broken on occasion for the sake of Art.

It seems that many of us with "modern" sensibilities accept (highly!) imperfect rhymes with nary a thought.

Loose rhythm, varying from verse to verse or even line to line, is also generally not a reason to disparage a song as long as it doesn't cross some undefined threshhold of cumbersomeness.

Stumbling prosody is less often forgiven, especially in ballads - we prefer our storytellers to sound like they are talking. But even this "sin" can be forgiven if the rest of the song is really good - especially if it's not intended to be taken "seriously". I refer you to the works of Tom Lehrer for examples (I happen to think his stuff is good - although others may not agree! [grin])

Here's another question... is it still a "good" song if the pitch range is beyond the capacity of MOST singers?
