The songs affected are consistent across everyone who is affected.
There are at least two other threads about this, if not more.
No, the issue has never been fixed. Does it work for you? Great! But issue is not fixed.
It isn't simply a US vs. abroad thing. I'm in the US and am affected.
It may be a connection speed thing?? --

If affected:
It is OS-independent.
It is Flash version independent.
It is engine independent.
It is browser independent.
--means none of those things have anything to do with it

You can sometimes get affected songs to temporarily work (and once they do, keep replaying a bunch because you may not be playing it again for a while) by letting it load as much as it can, waiting a bit, reloading the page, rinse, lather, repeat several times -- occasionally get lucky.

The affected songs may seem "random" but it is consistently the same exact songs which are affected for everyone who is affected. This is demonstrably, provably true.

The problem exists with the game or server or network and not on your machine. There is nothing you can do to fix it short of playing on someone else's Internet connection which maybe isn't affected.

IMO, the game or server is making bad assumptions about the network??? maybe?
