Pop music and your opinion about it.

I don't know what the sales figures are for albums with pop music, because there's no point in buying them if you can find everything for free on the internet.

You can find everything on the internet. But it's so nice to have a disc of your favorite band on the shelf (mostly, it just satisfies the owner's self-esteem and, in a way, serves as a decoration). The same goes for video games :)
