Bards and music

[geekgirl101]

So today I unlocked the ability to play music with my bard, only I am then told I'm forbidden to play any 3rd party music and there's been many reports since the ability was added of players being banned for playing 3rd party music and even some FFXIV music (which isn't even made clear in the instructions when you accept the terms from the NPC in Gridania that you can't play certain FFXIV music.)

So what does that mean? Am I allowed to play We Wish You A Merry Christmas or will I be banned?

What about 3rd party music where we've been given permission by the authors to make our own versions?

And lastly, what is the point? We've been given the ability to play music on an instrument and then told we can't play music on it. If we can't play music then what can we play? And if it's such a major concern that people are getting banned for playing music then why did SE bother adding the ability in the first place? I can't help but get the feeling that SE's playing a big joke on us.
