YouTube Video Anomaly

Sorry if this has been shared here, already but this video is an oddity, and I was wondering if anybody can explain it.

Warning: the content of this video is juvenile and potentially annoying.

The video ends - even displaying the 'related videos' screen- but the song keeps on playing.

Within the last few weeks it seems to have been fixed for some, but not for all.

Does anybody have any clue what's going on here?

Hey, that's interesting!

I downloaded the video just to see it, and it's true that something looks like is wrong. The lenght of the video is wrong the first time and then the second time it's "ok" (meaning when the video stops). I got both the .flv and .mp4 from the video and I only see this problem on the flv. Anyway, given that fact, something leads me to think that the creator somehow messed up with the compression and google's encoding didn't help, giving this problem (actual video lenght with audio is around 3:35, video only 7 seconds).

I didn't check really get a deep check into the videos to be sure, though. Probably will when I have more time.

Yes, that's right.
In the past the video would end and the music would continue playing. I'm not sure if it's still doing it for everybody - there seems to be a 50-50 split between people who see the video and music end and people who see the video end but hear the music continue.

Very bizarre.
