The take-away seems to be that album sales are falling, single sales are rising, but single sales aren't up enough to offset the drop from albums.
Questions that come to mind:
1. Is any of this due to people having a lot more to spend money on today? e.g. mobile phone plan, mobile data plan, TV provider, ISP, among many others.
2. What about the larger music industry. Live music? Selling music to businesses rather than consumers?
