I just had a thought.
If one day CDs become obsolete and mp3 downloads become the main thing, I wonder how this will work.
For now, stores like Amazon probably possess the CD and have the right to rip it into mp3 and sell the mp3 (but I don't know exactly; maybe I'm wrong).
But when CDs will become obsolete, will the companies themselves do the mp3? If so, on which support will they send them to Amazon or people? On USB keys? what will be the point of doing that instead of CD? Or maybe always 100% download? For those who don't have an internet connection, maybe it will be possible to go to a music store, buy the album online and put it directly into your mp3 player, or your own USB key?
And this bring me to the point of quality once again: if the music become only available through compression, so what's the point of doing a perfect sounding master if there's no way anybody could listen to it at full quality? What's the point of putting time and effort into doing a great sounding record knowing that nobody will fully enjoy your work?
Once again this mp3/compression thing is giving me headache.
