What happens 3 years from now when you've got bored of Spotify and all the music you are listening to now is missing from your owned collection??!!
You buy it. Or, stream it on whatever new service is available then.
Seems a waste of money, when I can find far more new music than I can currently afford to buy just by listening to 6Music all day for free, and Shazaming what I like.
I refuse to rent music, that £9.99 equals around 120 single tracks, or twelve albums downloaded or bought on CD that are mine, over the course of a year, even if I lose network access. I can't stream music during the day, in the car, or when I'm out around town, 1Gb/month data counts that out.
What happens to all the music on your CDs in 3 years from now when superDuperCDs are released?
Same as what happens to the CD's I started buying in 1982, which I still own, and can still play, but which have been ripped into iTunes for ease of playing on portable devices.
The CD's meanwhile, still exist as emergency hard-copy back-up.
There are a few, very
few, which have been replaced with re-mastered versions, but I think I can number those in single digits, out of several hundred albums.
