Why do you think clic rock fans call current rock music crap?

Theres a few new bands I like, but I like older music better myself too, and im only 22, the reason is you have about 500 different genres of music now, and its hard to find good bands when theres thousands to choose from, and most of the bands they play on the radio are garbage, back in the day they played good bands on the radio, and u didnt have to search for a good band cuz there was only a few types of music. Thats probably the reason why rock music isnt as big as it used to be, theres just to many styles.
