Google play is awesome. You can listen to full albums and mixed radio stations for just 8 bucks a month. You can even make your own mixes with no extra costs. I listen to allow of the Symphonic / Gothic metal. Groups like Nightwish, Within Temptation, Sirenia, Xandria. As far as stations on Itunes I like Poison Radio, Iron Maiden, Queensryche, plus the groups I already listed.
