I think it would be producers' heaven if they could have writing credits just for changing the tempo, the instrumentation or adding riffs. In songs like Gypsy or Rhiannon the music and the lyrics were there. The version we prefer is another matter, IMO.
Or Stevie could just make the booklet a little more precise, like:
Through the Fears
Music and Lyrics by Stevie Nicks
And just above every song :
Lindsey's personal and definite contribution diary:
09/06/05
Lindsey told me to cut the third verse
09/9/05
He added violins and bongos
09/15/05
He created a (beautiful) guitar riff
09/17/05
I decided to put back the third verse and he stormed off
09/22/05
We called a truce. I Keep my third verse and he can add vocal effects
And so on for about 3 pages for every song...
