Is there a quick way of checking online whether album/cd has parental advisory warning

Hi my dc aged 7 is getting into music and, while wanting taste to develop as it will, I want to put brakes on access to anything with adult themes ( as they say). Dc listens to all sorts but 2014 pop is not my strong point. I already refused to buy Prism ( Katy Perry) but have downloaded radio friendly versions of some KP songs from that album to add to Dc play lists on my ipod. Any handy websites?
