I'm able to listen to anything that was ever released on CD. That's quite a lot of choice.True. But you rent more (all) music. So can access more than you ever could buy. Unless you are very well off. If you need all of that is unlikely but I do love having the choice.
I have to buy the CD and wait for it to be delivered, but that doesn't limit the choice. I just don't have instant access, that's the only real difference between physical format and streaming.
