For those who feel the need to own the music vs renting/leasing whatever you want to call it. I already own far more physical media than I can play, I derive virtually no value from physical media I no longer play due to new listening preferences, tons of my vinyl and all cd's in storage with difficult access to. Since my listening preferences constantly changing and evolving, at least some music becomes obsolete, don't need or want more obsolete possessions, already far too much of that.
The other thing I love with streaming is the ability to access my music via smartphone at workplace and in car. Long trips made far more pleasurable with this.
