Seems like a great idea for an app. You're at a store like Walmart, and you see a CD that catches your eye. You scan the barcode, and can now click on each track to sample each song right from your Android phone. Lets you know whether or not you want to buy it. Some stores already have something similar, but not all stores have it and not all stores have it for all CD's. I'd like to do it from my own phone anyway, than to put on the greasy lice infested headphones at the store anyway lol. Yes, I know I can just buy the songs on itunes or Amazon, but sometimes I like to have the actual CD, and the mood strikes me to buy a physical disk now. Does this exist?
