" We&amp;#039;re not normally ones to agree with John Mayer, but it&amp;#039;s difficult to argue with his sentiments regarding his girlfriend&amp;#039;s new single &amp;#039;Roar&amp;#039;, which he recently described as a &amp;quot;megaton bomb&amp;quot;-sized hit. So far his prediction has been pretty spot on; the track has given Katy Perry her strongest first-week sales in the US to date - no mean feat when you consider the omnipresence of her Teenage Dream efforts.  Based, she says, on her time in therapy since her last album and the breakdown of her marriage to Russell Brand, &amp;#039;Roar&amp;#039; unsurprisingly takes the positive mental attitude approach to overcoming ones woes. &amp;quot;I got the eye of the tiger, a fighter, dancing through the fire,&amp;quot; she sings over rumbling marching-band drums, before belting: &amp;quot;You&amp;#039;re gonna hear me roar-oh-oh-oh-oh&amp;quot;. It may sound like self-help for dummies, but it works a treat.    Listen to &amp;#039;Roar&amp;#039; below:      "^^<http://www.w3.org/2001/XMLSchema#string>
