You can't compare iPhones to CDs- Digital music to CDs, or mp3 players to CD players, but iPhones and CDs are not equatable.
I rarely, if ever, buy CDs anymore. I can Google the lyrics if I need them, I don't care who plays the bongos on track 4, or if they thank God, and all the pictures are available online. I don't want to spend $15 to buy 12 songs when I only like 3 of them. I don't have the space to store hundreds of CDs to add up to the music collection I've acquired online. If I'm causing the downfall of the music industry, so be it, but I've wasted money on too much crap over the years to willingly perpetuate the system.
Like a firework unexploded
Wanting life but never
