Is there a "vinyl renaissance"?
Yes, of course there is.
That's why we are talking about it.
That's why there have been numerous threads about it on ASR and many other forums.
That's why it's become a ubiquitous news story and entered the pop culture consciousness.
It's why there are forums devoted to it. It's why audio stores, including big box stores, are back to selling turntables. It's why stores large and small are selling vinyl.
Nobody is of course claiming vinyl is going to actually compete with streaming for market share. That's just a sort of strawman approach to understanding the phenomenon.
The point is vinyl, which was seen as "almost dead and headed for extinction" revived it's fortunes, has been selling more and more every year for 15 years, even to the point of entering popular culture again. Most popular artists now release (or want to release) their music on vinyl. The powers behind marketing and sales are making vinyl part of the sales platform
because of this sea change regarding vinyl. They couldn't make a "chunk of cash" as you put it, on vinyl, if this significant change in vinyl popularity hadn't arisen.
It's now pretty standard for even minor or indie bands to want to release their music on vinyl. My brother is a tiny indie musician and it was virtually a given that he'd also release his music on vinyl.
15 years ago none of this would have been the case. There are constant news stories on how the demand for vinyl far outstrips the capability of producing it, so bands are waiting up to a year or more sometimes, to get records pressed. So there is even more demand than even the sales reflect.
15 years ago I had a single dusty old hold-out record store within walking distance. Now there are FIFTEEN within about a 2-4k radious of my house. I go in there and they are usually busy with people of all ages buying vinyl. When my son's friends come over and see my turntable etc, vinyl is no longer some weird mystery thing, more often than not they say "Oh yeah, we have a turntable and records too."
This is an entirely different scenario than we had 15 years ago. It's why we are talking about the vinyl renaissance now, and why there are stories on it almost every day in the news.
So, if the point of a graph like that is to say "Look how much more popular streaming is than vinyl" that's hardly news. But if it's to imply "there isn't really anything signficant in the purported vinyl renaisance" that would be pretty misleading and missing the point, IMO.
