Spotify Discover. It would recommend you artists/albums/tracks related to what you listened a lot.
 
Also, I often manually search for artists I don't know by checking their 'related artists' on Spotify. If they have more than 3 or 5 related artists that I like, chances are I would like them as well.

For classical music: I rummage through CD bins at used record stores and follow my instincts.
 
For classic rock: I immerse myself in a particular band to the point where I end up buying all their albums over a few months.
 
For indie rock: My daughter - what she likes, I usually end up liking as well.

It really depends. The discoveries variate from either self-discovery or recommendations. Presently, I've discovered Last.fm and have found the website to be a very useful tool in music discovery. Another wonderful website for music discovery is Pandora. However, a habit I have recently picked up ever since venturing into Vinyl is picking records based solely on their artwork. This method is definitely a hit or miss but I've been lucky so far. : - )

Wow looks like this thread has been getting some use.  Sorry for the inactivity on my part.  I will try to get the first post lined out with the suggestions here.

Give http://rateyourmusic.com/ a try. You will get recomendations once you rate some albums.

To add to the Rate Your Music recommendation above, I would suggest taking a look at the different charts to possibly find some new gems you've never even heard of. Below are links to some examples of custom charts, but feel free to experiment with different search criteria to tailor the results to what you are looking for. All charts below include sub-genres along with archival and live releases, where applicable.
 
Top albums of all time
 
Top albums of the 00s
 
Top jazz albums of all time

Top metal albums of all time
 
Top metal albums of the 80s
 
Top sludge metal albums of all time
 
Esoteric albums from all time (highly-rated albums with a small number of ratings)
 
Edit:
Don't forget to search for EPs too!

^ Of course that is the site's best feature. No idea how I could forget to metion that

Have only skimmed this thread, so I may have missed this somewhere in the middle, but aside from reviews (NY Times, JazzTimes), I find listening the the WFMU.org streams (they have a few, with live shows, archives, themed threads) lets me hear music that I wind up searching for within minutes. Worth a listen (reviews are nice, but hearing something that knocks you out can't be beat). The "Give the Drummer Some" is particularly great if you're an omniverous music junkie-they play everything, rock (old, current), jazz (20's, bop, free, swing), country, international...no classical, otherwise stuff you may never hear anywhere else!

Sorry guys.  Finals are coming up and I have been swamped.  I will have the OP fixed up by the end of December. Keep the good ideas coming!

In addition to the radio stations on this page http://radiobit.50webs.com which includes the 320 Kbps Linn stations, I have done some listening to Pandora and to iTunes Radio. This is a service similar to Pandora, it is free with a few ads, but it sounds pretty good despite what I assume is a low bit rate.

My reference wasn't to Pandora which has the bit rates you mention, it was to iTunes Radio which is similar to Pandora but I think sounds better. I don't know the bit rate of iTunes Radio but I assume that it is pretty low. The 320 bit rate for Linn Classical, Linn Jazz and Linn Radio sounds better, of course.

 

[GrindingThud]

Ah, ok. I love the Linn streams. . I've not used the iTunes Radio much yet.....

Mog is like Spotify and some of the other streaming sites, has higher bit rates than many and good sound.
