Well yes, those who want the CD will buy and those who want to stream will stream. But what happens is, as streaming becomes more and more popular, music companies will decide to stop producing physical albums because it will save them money. Then we have to conform to the streaming lifestyle.
The only reason things are balanced now is because there are still many people who are old enough to know the value of collecting music. The kids of today and the future will all be born into this streaming format, causing the death of music collecting.
But you're welcome, I always like to hear what people think. I'm glad you are optimistic.
