Query: Whatever happened to rock 'n roll?

Too many bands could mix up their members and release CDs without us knowing that there'd been a line-up change. This is one of them.NICKLEBACK's offering is staid. Did i say NICKLEBACK when i meant to say THEORY OF A DEAD MAN? Easy confusion when Chad Kroeger's the co-writer and producer ... and the lead singer sounds like him. The best track by far is 'Nothing Could Come Between Us' and will undoubtedly be a huge hit but the rest just became too much for original-wanting me.
