Did the group sign over all their residual rights? That would fatten the pot.
Are residual rights a thing in the music industry? I thought that was mainly films and TV...
Hum... digging into it... in music it's more royalties, it would appear, for the creators, song writers, composers, etc. I'd assume that in some cases performers might get royalties for perform.
And, since Queen created mostly all of their own work, I guess theirs would be royalties, and I suspect that that is where a lot of the value is. If Sony isn't having to pay out royalties to the members, that increases the value of their tender... So, I'm guessing, but not 100% sure, that yeah, that $1 billion includes full control of the catalog with not further royalties to Queen.
And, I just just remembered a story I heard about Dolly Parton...
She had written and performed "I Will Always Love You" and it was a pretty big hit for her.
Big enough that Elvis was apparently really interested in doing a cover of it, so his manager, Tom Harker, contacted Parton to cut a deal.
Only, the deal was that if Elvis covered the song, Parton would sign over half the publishing rights.
Dolly Parton essentially told Elvis to take a hike.
