Query: What Rock n' Roll should be

This CD is what Rock music is supposed to sound like.Rick Springfield is truly a gifted musician who improves with each new album. SDAA is his best work without a doubt.Each song sounds different, unique from the one before.The stand-outs are the bluesy "Alien Virus", "Every Night I wake Up Screaming", "Jesus Saves", "Will I?" and what should be the next single "Wasted". But again all 17 songs are great!Rick Springfield Rules!This CD is highly recommended.
