How could he release something probably which he hasn't got? It's human nature, we all voice our opinions or criticise especially if something is n ot to our liking.
I think he has every right to *** them off. Like him or loath him...he a song writer and a musician...which puts him into a different league to the likes of Cheryl Cole.
He has always been known for being outspoken about a lot of things and from a performers point of view anything that gets him in the news is a good thing.
I think he has earned the right to criticise other performers music, like him or loathe him he had proved over the years that he has genuine musical talent which is something a lot of modern "artists" are somewhat lacking in.
Why do you have to be in the top ten before being allowed to speak? You *** people off all the time, and with far fewer credentials than Elton. Since he's retired, he doesn't have to make new music.
