Google+ trends: Steven Tyler leaves 'American Idol,' #FidoFriday

“I strayed from my first love, Aerosmith, and I'm back -- but instead of begging on my hands and knees, I got two fists in the air and I'm kicking the door open with my band," said American Idol judge Steven Tyler.

“I have a huge amount of respect for Steve Tyler as a musician and as a singer.  He's a great artist but unfortunately I do not find him to be a great singing competition judge. It's great to hear him return his focus to his music. I'm looking forward to hearing more of his new work!” say G+ers. “Rock 'n' Roll SHOULD come first!”
