YouTube unlistenable

I don't see anywhere in my post that YouTube is my reference source, but sometimes want to see occasional performances of musicians. Some of the tubes are on HD format with at least MP320 format, but that doesn't realy matter. The point is I used to browse tubes with no interruptions of some dummy commercials on the right or left side of the page. "Congratulations You Won!" while listening to performance. It's damn wrong for the site to be compromised by hackers.

I double-checked my popup settings and the blocker is "on"... Should I security settings to highest? It's not happening with most of the sites I visit...

Dick, That's exactly the artist I was listening to! The performance is stunning... so clean that I would even listen to it in some poor format such as MP96. Also I recommend to check the same piece by Ana Vidovic(WOW enjoy the views of the sexiest classical guitarist!)
