In early July the music charts are going to include streaming statistics when they are compiled. Services like Spotify, Deezer, Napster will be included. It will be interesting to see whether this makes much of difference. I used to religiously listen to the chart show on the radio when I was a teenager interested in such things but my interest has waned considerably since those days. The music industry has changed so much since the early days. I reckon most acts now make more money from playing shows than they do from royalties but I suppose royalties can pay for years into the future. Writing a successful Christmas song seems about the best way to make a lot of money for not doing very much.
I listen to some music on Spotify but I only have a free account. I have considered a paid account, mainly to avoid the adverts, which are very annoying.
