Doesn't it seem like these things are becoming a bit over the top? In the last two days I've been sent 2 links to 2 different extreme mash-ups. Check these out and then ask yourself if these games with sounds are really creating more than a giggle and a burp. Sure, they glorify the mashability of the particular creator, but really how much do we need to be impressed. Particularly if it comes at the expense of good music:

The Beastles: A mash up of (you guessed it) Beastie Boys and Beatles. What has Danger Mouse foisted upon us?

The Who Boys: The Who and The Beach Boys together as, perhaps, they should never be. With beats.

Not to be a sourpuss, it's all good for a laugh. But it's getting a bit over the top, isn't it?
