Yep falling in line with Tidal and Qobuz as they all want to get it ($$) while they can. Now of course quality over quantity has to be key somewhere. I guess we shall see.
The original article is old news and has been superseded by announcements from Apple Music and Amazon in the past several weeks. Both of them have announced CD quality streaming at no extra cost (Apple) or lower pricing (Amazon). That makes me doubt that Spotify will be increasing prices if they want to remain competitive.
Not in the times we live in ... Amazon, Tesla, Apple, Housing Market, High-end Audio, LP albums, music cables, 4K Blu-rays, speakers, amplifiers, DACs, oil, climate change, timber, yachts, mansions, luxury cars and watches, Netflix, whiskey, ... everything must go ... up.
