Right gdnrbob, no one is stopping anyone from buying anything, but with streaming you listen on your own system as many times as you want before you buy and you can sample so much more music.
The music industry has always had their hands on the throats of music buyers. They have always decided what you hear, what it sounds like and what it costs.
I am sure that I have more Lps, Cds and Cassette tapes than I will have time to listen to before I die. So, except for music that is really special, why should I keep piling up more?
I don’t trust the music industry either, but all things must pass, as some musician once said. You should try streaming before you decide you don’t like it. You may be surprised.
