Stevie/Mick argument question

[bwboy]

Stevie was upset because she wanted to put Silver Springs on her TimeSpace/greatest hits CD, and Mick wouldn't allow it, because he wanted to put the song on the Fleetwood Mac 4 CD Chain box set. Of course, they made up and the rest is history, but my question is, since Stevie wrote Silver Springs, how was Mick able to withhold the song from TimeSpace?

This is especially puzzling because in a recent interview, Stevie said her Joan of Arc demo was originally going to be on the Tango Deluxe edition, but she "pulled it" because she plans to record a new version later. So Mick was able to withhold SS from her album, and Stevie was able to pull Joan from a FM album, so I'm really curious as to how the band decides these things.

For example, are all of Stevie's songs she recorded pre-Bella Donna really the property of Fleetwood Mac? Because I really don't understand how Mick could have unilaterally made the decision to put SS on the Chain, unless Stevie agreed? Has Mick or any of the others ever spoke about how they figure these things out?
