1) Ping is only available in the US, so a straight comparison of user numbers to FB isn't necessarily valid. You have take the number of US users of both iTunes and FB, and I don't think that breakdown is readily available.
2) Non-mainstream stuff is likely to be overrepresented in these sorts of things, since people who are into to music are more likely to use such new music services and are also likely to have more varied tastes.
My point is still valid though. To do proper comparison for Band of Horses, you have to take # of users in native English speaking markets. For FB, that is not the majority, though it is a large plurality; for iTunes, it may very well be the majority. Apple products aren't a significant part of the market in SE Asia, but FB is.
This way the focus is on, look Apple fixed their mistake and it actually serves a purpose now.
This button is just a little shortcut for functionality that already existed but was ridiculously inaccessible before.
It's actually a pretty minor change, but obviously there was some confusion of how Ping worked, so the UI change seemed necessary.
Now you can "Like" stuff directly from your Library.
All they've done is replace that little arrow-button with a pop-up menu. It's a pretty small change, overall, it just makes things more obvious.
