It seems to work fine with any music you use, almost - and it seems they have tackled the problem in a different way now, instead of removing or closing the audio/video.
You get a little add in the lower side of the video that can be clicked away, when using YouTube.
(Vimeo is not good anymore IMO, as it does not allow free HD video upload like YouTube)
And sometimes in one or two countries the video is blocked (but I've only experienced Germany and Japan as those yet, so not a big problem for us).
But it might be different in other locations ?
And I know for sure it depends on the actual music and rights too - very different "claims"
