I don't think the Covid is going to change Music of the Spheres, that would not match the hint that they left in Everyday Life, here the reason why the album has not been released yet, is because maybe the band could not finish recording the album , or they want to release the album on a date where everything has settled down and they go on tour and most likely they couldn't trademark the name
I think that Music of the Spheres will be the same from it's conception in 2018
But MOTS as a title obviously remains, so the ideas for some of the songs probably have stayed untouched. Would have been interesting however to find out how much the course of the album has changed in the past year since the pandemic. I am 100% convinced this will also be included in the theme.
