That would be logical. This thread is the first I’ve heard of this so didn’t know they hadn’t said anything (I didn’t read the article in the OP of course). It’s nearly always the publisher that instigates things like this rather than the composer. If I remember rightly, this is exactly what happened in the Air That I Breathe/Creep case, the Hollies saying it’s not us, it’s the publishers.
Maybe Thom’s working on a big statement where he can somehow blame Spotify for it?
