Or, the old quote, "The rich get richer and the poor get children..."
The trends noted here are the natural result of the cultural downturn in musical activities and the shift towards streaming -- where you can get anything immediately at no or low cost.
Who is going to spend huge amounts on a system in order to stream MP3 files? Well over 60% of current listeners stream only and this delights the small crowd controlling the process because they can ensure some revenue from each listen. But musicians lose.
High res MP3 (LOL) and MQA files might move this large crowd towards higher end audio equipment but there are a lot of unknowns. Who would have thought that Spotify would get the kind of stock opening it just received? As with Amazon and Google wonder if the big money has made its choice for the music streamer of the future.
