I rarely hear a Prince song on the radio, they’re all pulled down from YouTube as soon as someone put them up…And I rarely visit brick and mortar rcord shops and I don’t do MySpace.
So where do you listen to Prince songs and buy them? And does the man still make video clips with his songs?
I’m a big Prince fan so I buy his albums without hearing them, even though I think he’s been on quite a decline lately. I guess with each new release comes a flurry of publicity because it’s Prince, and you can often listen to new singles through his website. Other than that there really aren’t many avenues.
The YouTube thing will only hurt him, the longer it takes for him to realise this the more new fans, exposure and money he loses. He’s evidently not worried about that, but I believe if he really cares about his legacy he should make it easier for people to find out why he was such a huge star.
Try Amazon’s The Prince Store. I don’t know if that’s everything, but it’s a lot.
His only competition is him in the past. 
We get our new Prince albums at a music store still, I think. We buy them without listening, too - we have almost every album he’s put out, and they range from good to unbelievably good, so we’re not too worried.
