Not sure if I’m reawakening a controravercial subject here…
Back in 2017 (Cat Stevens→Yusuf Islam merge), there was a proposed merge and susequent discussion if the entries for Cat Stevens and Yusuf Islam should be merges - with the outcome that they weren’t.
Now with Yusuf / Cat Stevens’ latest release “Tea for the Tillerman 2” perhaps its time to reexamine.
I’ve added a release for the CD of this, https://musicbrainz.org/release/db151046-9bb2-4427-ba29-6636cebbd84c and while doing so have altered the release group credit from Cat Stevens credited as Yusuf / Cat Stevens to Yusuf Islam credited as Yusuf, Cat Stevens separated by " / ".
My own vote would be that Yusuf Islam and Cat Stevens’ should be merged, they are not (as suggested for separate entries) imo separate “projects” but an evolution of Yusuf Islam as an individual and an artist.
