That's what every old fogey says! Actually I do agree with this. When I look at what has happened to the punk music scene. Even what has happened to Green Day. Dookie was an amazing album but they have fallen so far since then. The Clash and Ramones have been replaced with All American Rejects and Simple Plan.
Of course, rock isn't what it used to be anymore. Hard to find any bands now that can compare to bands of the 60's/70's/80's. Honestly, the only recent band that is still around that I care for is Black Keys.
