No worries, I’ll take your U2 example and try it from my end (I don’t listen to them so I can’t decide on what album(s) specifically you are looking for). I’m going to be frank, it was a pain, but I did find zdigital (7digital outside of Australia) selling their albums without physical media. But getting there, I had to see that the U2 website/publisher website did not even advertise it. It was like the 5th option on duckduckgo after searching for

I’m sure you would have better luck if you slide in the specific album that you were looking for.

Important to note is that you aren’t googling for that artist or album, you’re googling

I do agree with you that mainstream artists and publishers are going down this route probably due to some deals with streaming services, but unfortunately that is the reality we live in now. Additional work will be required by the consumer to get what they want. If the publishers start completely stopping this at some point all I can say is that I have the disposable income to buy the products I want and I am going to get it. Whether the publishers sell it to me or not is their decision to make.
