London, Mar 10: Music lovers who are addicted to watching online videos on Youtube will not be able to do so anymore as Google has blocked viewings after a dispute over licensing.

Google had started blocking UK viewers from watching "premium music videos" from the night of March 9.

Google described the move, as a "painful decision" which it knew would cause "significant disappointment".

The legislation was adopted 96 to 56 while 47 parliamentarians were absent at the final reading of the bill.
