What do you use to listen to free music?

I would recommend The Spotify communicating via facebook :)

Pandora or grooveshark

Arrr

last.fm/ , tbh I usually don't listen to radio stations all that often, but when I do, last.fm/

I really liked the internet radios that Beat Hazard has, but I only ever looked up one of them on the web (and never really listened to it beyond playing Beat Hazard anyways).

I use soundcloud as well, I definitely prefer it for linking songs to friends in lieu of youtube, since there is a much better chance of getting good quality when you find a song on soundcloud compared to on youtube

bandcamp has some free music and you can steam from their site too, but lately I've been getting super long load times on that site :<

if I look for something in particular grooveshark or youtube
else morow.com

I can't use spotify or pandora :(

and if you want to discover new artists, last.fm is for you

used deezer a time ago... maybe worth checking out

youtube 'cause there's so much to see (omg you can never un-see some of these things!) and hear, and then while you have the time, go to e-bay and shop while you listen to music while you're playing a game in sandbox :D

google

8tracks.com and plug.dj

8tracks - people make a playlist of songs, offer up a bit of background/info for it, and users have kind of a spread sheet or so. Imagine walking up to someone who has a box of old mixtapes in their hands, and rifling through it. Kinda like that. Found a lot of good music on there, and just things that fit my mood at any moment.

Plug.dj - similar concept, website has a kind of mockup of a club with all your avatars on screen (yourself being front row of the "stage" and people can join a queue to "DJ" music, which is basically them hosting a song they have on their playlist, either from soundcloud/youtube/etc. Once the "DJ"'s song(s) are up, the next DJ steps up and you hear what they got. Upvote/downvote feature kind of thing, and you can add songs you hear to your playlist. Another good way to find new music in a genre you enjoy, while getting a feel for what others like too.

I usually use Youtube mainly because, most of the time I know what I want to listen to. Other times I'll just go to Pandora and type in my favorite band's name and listen to some great bands similar.

My favorite band is Green Day. I like to listen to Post-Punk, Heavy-Metal, Classic Rock, Hard Rock, Alternative, Pop-Punk, and stuff like that mainly. I'm not too in to the Electronica type thing, but that's just my preference.

A few other great bands you should ALL know:
Metallica, Pearl Jam, The Killers, R.E.M, AC/DC, Simon and Garfunkel, The Beatles, Van Halen, Black Sabbath, Ozzy Osbourne, The Doors, Weezer, etc.

Hope I helped in some way :)

I mostly use my MP3 player + mp3s lately. Today I tried Noon Pacific for the first time. It was a good mix.

torrents + windows media player

free music is free music, only this way I only have to use bandwidth for a song once

Grooveshark since it scrobbles :3

If you like house, electronic, edm, etc., maybe make a tumblr and use it to follow a lot of the good blogs that focus on those genres. The Hype Machine is useful too, there a few really big music blogs that post a shitton of house/edm/electro/dubstep/progressive/etc.

I like a lot of the same stuff, especially french touch/disco-house/nu-disco, so here, have some recommendations; links are to some of my favorites:

Daft Punk (of course), Grum, Gigamesh, Moon Boots, Lemâitre, Treasure Fingers, '96 Bulls, Oliver, DCUP, Lenno, Monseiur Adi, Louis La Roche, Madeon, L'Étranger, Plastic Plates, The Aston Shuffle, Teen Daze, Robotaki, Phonat, Mix Chopin, Jonas Rathsman, Moonchild, Final DJs, Röyksopp, Shook, Melee (formerly Melee Beats), Danger, Russ Chimes, Bit Funk, Eumig & Chinon, The Phantom's Revenge, Bag Raiders, Mord Fustang, Jupiter, Breakbot, LBCK, Fenech-Soler, Pablo J & TheLobsterettes, Aniki, Ocelot, Cherokee, Perseus, Arcade High, Pyramid, Fear of Tigers, DJ Kue, Irish Steph, Tycho, Calvin Harris, Clock Opera, Kavinsky, Gramophonedzie, Le Knight Club, Anoraak, Zimmer, She said disco, Jungle Fiction, Moullinex, Blue Satellite, la Zebra, F.O.O.L., RÜFÜS, Volta Bureau, Viceroy, Damn Arms, Futurecop!, Lifelike, Fred Falke, Justin Faust, Kris Menace, The Knocks, Classixx, Popular Computer.

If you can't find anything new that you like in there then I'm sorry, I can't help you (and sorry about your taste in music)
:)

Torrents for download. For listening I use AIMP3(on pc) and Poweramp(on adroid). I'm mostly listening to edm and dubstep. I had a thread about this on the forums right here if youre interested in reading :). I discovered a lot of great stuff from these guys.

spotify, though not entirely free it's a steal @ 10€ / month.

I usually use YouTube to listen to it, and if I like the song, I download it using YouTube2MP3pro.
