Does anyone have any suggestions of new bands that I should download?

I would suppose that depends on your tastes. If you're into rock music, check into Icon for Hire. XD They're so good.

I only know Asian artists ...Sorry D:

if you like asian artists, you should really try yiruma.
he's a pianist, composter, and a ballad singer. it's
quite nice <3

i also suggest hirasawa susumu, he's quite a crazy
guy. he's an awesome composer and he even sings
in some of his crazy trance songs. o u ob lots of
different types with him.

then there's yamazaki masayoshi, sort of an old school
artist, but lovely none the less. made my life song~ <3

Hard to say without knowing what you are into XD

Here's some that I know of that aren't super common:
Ludo
Kerli
Bif Naked
Eisley

Hope you like one!

Don't know your taste, but I'll take this opportunity to splurge about my own!

Janelle Monae- a soulful voice with an eclectic style. Her latest album goes from symphony orchestra, to RnB to rock to pop to operatic! I love the variety of one album! Made me buy both her official albums. Now I've got to look for underground stuff.

St. Vincent - she's airy and artistic. Her lyrics paint vague images that allow your mind to come up with its own theme of the song. Her voice is very beautiful.

Gotye - All I heard was "Somebody I Used To Know" and it was enough for me to buy the album, Making Mirrors. I certainly don't regret it. I'd say he's an alternative style. All three of these are, really.

Freezepop - Have you heard of them? They're a techno-rocky pop band. Pretty different. My favorites are "Less Talk More Rokk" and "Brainpower"

Jamiroquai - a funky guy. His music is like revamped disco! lol I love it. He did "Canned Heat" used in Napolean Dynamite and Center Stage.

Hiromi Euhara - for those of you who enjoy piano jazz. :3

Most of what I listen to is asian music ;
SPYAIR-Just like this!!!! - YouTube
If you're into Japanese stuff, I suggest the above group "spyair" & ONE OK ROCK :lol:

If you're into pop/or r&b stuff ; try big bang, 2ne1, SHINee (All Korean ♥)
SoulJa - "Hanasanaideyo", "Breathe" & "I Hate You" (ft. ROLA x ISSA)

Electrocitica - "Reversus"

And then for English, the only suggestions I really have are Gotya - "Somebody that I used to Know"
haha
And some crunk.... but I have a feeling you wouldn't listen to much of that :/

Hopefully you find some new music though! :3
