What are your sources for dicsovering new music? I certainly know good music from after 69, but in recent years I have been slacking in my research. I don't think it would be fair to judge current music just by the stuff you get to hear on MTV or radio.
I usually discover new music by 'accident'. For example, on radioblogclub.com you can search for artists or songs you know and you end up with a playlist you can listen to online. After you've listened to what you were looking for, you can keep listening the playlist and discover similar stuff.
Web radios are great, too. A favorite of mine is www.scenemusic.net (old-school demoscene music).
