Since I have been called a pedant by you before, Joe, I am not going to play the teacher here. All the more since English is not my native language, and in fact there is no language of which I am sufficiently fluent to pose as a professional lyricist.

But I feel entitled to some general remarks about aesthetics. First of all, lyrics intended to be colloquial must by all means stick to their style; "Hound Dog" mentioned above is a good example. (As discussed in many other Mudcat threads, singers who come from a different background may not always want to imitate the original diction.)

I do not know whether "between you and I" is a true colloquialism. It may well be "hypercorrect" usage by people who have been told that "you and me" is usually incorrect grammar. Writers would not like to be caught with such a blunder.

Secondly, nonstandard language deserves licence according to its creative value and formal brilliance. This notably includes "crazy" rhymes in the most funny American tradition - "under the hide of me". Unfortunately, many popular lyricists fall short of that category by far, and would so even if their grammar and spelling were flawless.

Nonstandard spellings that reflect a particular pronunciation or emphasis are absolutely all right, even in literature. "His spelling was not all right, but that's alright with me."

Even the best writers and other artists are not always perfect. Not even me.
