Lady Gaga sold 9.8 million downloads? And piracy accounts for 95% of the downloads? That would suggest that Lady Gaga was downloaded 196 Million times. Shockingly, if the industry was forward thinking enough to lower their prices enticing the pirates into buyers of music at $0.10 each, they would have doubled their income. Instead they keep prices high and lost sales.
I think that there's a disconnect between listening to music from the radio and buying a CD to listen to music in a stereo. Stereo's are no longer the hot thing and are a commodity item replaced by computers, phones and digital music players. Even some factory car stereo's include a USB port to import music to the included vehicle hard drive.
What hurts digital sales is that music has become a commodity. No longer do you need a recording studio to produce a good single. These days a Mac, and a YouTube or MySpace account is enough. The record industry still has a distribution channel, but indie artists can get into iTunes without much effort.
One of the detractions from a recording industry is their DRM which limits where you can listen to that music. People want to share music with their friends, and why not when it's free over the air waves in radio and in the Internet? And I agree with the others here who describe the quality of the digital downloads as being inferior to a lossless compact disk recording. So digital music should be sold at a lower cost.
Finally, I agree that the prices are too high. I'd argue that the bulk of the pirates are under the working age and can't afford or have no means (credit cards or elsewise) to easily purchase music, yet it's readily available on the Internet. To them it's like picking a fruit off the neighbors tree, instead of buying the fruit at the store. It's available and right next to them seemingly at all times. With the needs for a studio going away, the nature that music is freely available any ways, and that people want more ways to listen and share music - the industry needs to take a u-turn and take a cold hard look at what they need to do to please their customers.
