I'm pretty dependent on music to get any work done. The only thing is, each album's usefulness has a pretty short expiration date so I constantly need to find more.
At first I used to use Youtube's sidebar suggestions. Most if not all the suggestions are the particular band I would be currently listening to. Subscribed to a couple labels for a while as well.
Then I tried Pandora but they don't have many of the bands I want to find similar stuff to and rather have a list than random play.
Last.fm was working out alright until I noticed what they took into account for the similar bands. Such that if I search for a Japanese band I don't actually care if they're from Japan as long as the music itself is close to what I'm searching for, but all I get are Japanese bands. Just decided to search for the Chicago based band The Brokedowns that KG posted. It mostly gives me a bunch of bands around the Chicago area. That confirmed that.
Reddit's ListenToThis subreddit is nice for finding stuff I would never have thought to look for.
So yeah, is there anything better you guys use? I've seen a couple sites that use branches but I don't remember what they were called and didn't have a lot of what I searched for.
Not big on random radio play since I rather not have to keep skipping songs that don't mesh with me.
I guess I kinda use last.fm. Not that much though, I haven't been able to listen to music that much lately..
And I recently discovered MySpoonful, and really like it. They talk about new/rising indie artists, three times a week. Some of them are really good, and the fact that they're not mainstream makes them even more valuable.
I also will search by genre on google, things like: "Underrated black metal bands" or something like that.
Reading reviews is a good way to get pointed in the direction of new music. I go to Sputnik Music. I read Pitchfork every week or two.
The radio and TV. I find myself listening to the radio in my car and I constantly mine lyrics to google for later when I hear a song on TV.
At this point I have experienced so much music that I largely will search for new bands based on my current mood. For example, if I am listening to some Dub Step or IDM or Techno in my collection I'll google around for similar or new bands.
But definitely check out those two threads, they are full of SHITLOADS of amazing music. Epic stash.
