Help me discover some new music...

Rebbi do you use Spotify or MOG? It's free but with commercials every 5 songs or so. My wife and I pay ten bucks for premium service. No commercials and we have access on our iPhones and iPad and can just hook right into my main system, or listen on the go or in the car.I highly recommend this approach for you as you have access to 30 million songs and really complete catalogs from most major artists. You can sample tens of thousands of musicians before you buy CDs or decide to listen to Spotify or MOG without buying the CDs . Spotify and MOG do offer suggested material when listening to an artist.
Here are other great ways I find new music.
Pitchfork , online music mag. Search for the best reviewed albums, although they have panned albums I find near perfect.
Best of music threads here. I discovered Ben Howard this way.
On AudioCircle I look at what are you listening to now threads. Also in the Salk Circle there is a fantastic thread on reference recordings with great music of course.
NPR , First Listen and Tiny Desk Concerts and listen to public Radio.
My wife explores a lot of new music and sends me the bands she thinks I will like. Lucky my wife is a musicphile.
As others gave mentioned , branch out from classic rock to Alternative Pop, Alt. country has been a revalation for me and I dislike Country music. I discovered Jazz a few years ago as well. Blues and Bluegrass can be great as well. I listen to a lot of male singer song writers such as Ray Lamontagne and David Grey, Martin Sexton etc.
Sample, listen, explore, branch out, and most importantly discover new music that makes you happy.

The music scene is in a dismal state these days. Not a lot of talent, but a lot of copy cats and celeb wannabees making tons of money being 'famous'. Most would not have lasted 5 minutes in the 60s / 70s. So, don't expect too much. I have been listening for decades, and I still listen to the "same old stuff", because nothing has come along that's better or even interesting. I now live off reissues, remasters and sacd remakes. The fact that the Rolling Stones are still around, and popular, speaks volumes.
Your tastes may be different, but whatever the genre, it ain't what it used to be. Classical Music excepted. Good Luck
Cheers

Rok2kid , the only thing dismal is your attitude. You are so wrong. So keep your ba humbug attitude , and keep listening to the same old crap. I really pity closed minded people.
There is tons of great music coming out everyday, but you will never enjoy it , because you are negative.
Certainly , don't discourage others who yearn to seek out great new music, to adopt your ridiculous notion that there is no great new music.

I have to agree with Toddnkaya that there really is a lot of great new music out there. The only issue is that so many people listen to the same old stuff or bad pop music, the great new artists don't get any radio play. I listen to NPR and my local public radio station because they're the ones spinning the great new artists. Try listening to Mountain Stage or World Cafe. I actually think things are getting better, not worse. You just need to know where to look. NPR Music is a great app if you have an iPhone.

Rebbi,

you are off to a great start. I find much new music listening to NPR.
