Just curious as to how important the lyrics are for those that use BIAB to compose original songs.

Personally, I love BIAB because it has allowed me to concentrate more on my lyrics (which is my real passion) as oppossed to spending time hours/days/weeks trying to create decent tracks that I can pitch to publishers. BIAB has also allowed me to write in genres I never would have imagined before!

How do you rate the importance of lyrics and what methods do you use to improve on writing lyrics (e.g. songwriting books, song evaluation services, BIAB forum, etc.)?

Do you write, re-write, and re-write until you've beaten every line (aka, made it the best it can be)?
