Timespace era

This is something I wanted to ask but always forgot.
What exactly is Gentoo Music, Inc. ? Who owns it? And what exactly controls?

The Rumours booklet says:
All selections published and controlled by Gentoo Music, Inc. (BMI

Easy to find out Lindsey's and Stevie's. Christine's songs are controlled just by Gentoo Music, there's no second entity. So I asume Silver Springs, like Dreams, is controlled by by Gentoo Music, Inc. and Welsh Witch Music. But what exactly do these entities control?
Does this has to do with the SS issue with Timespace?

PS: Couldn't find my old white cd album booklet, but I'm almost sure it just mentions Gentoo Music Inc. It seems Now Sounds Music and Welsh Witch Music didn't exist yet.
