I'm in a bit of a mellow rock/singer-songwriter mood lately so that's what I'll mostly suggest
Iron & Wine, Band of Horses, The Mountain Goats, Fleet Foxes, The Strokes, The Shins, Joshua Radin, Cary Brothers, Sara Bareilles, Ben Harper, Passenger, City and Colour/Dallas Green, Damien Rice, Bright Eyes, Death Cab For Cutie, Ed Sheeran, Edward Sharpe & The Magnetic Zeroes, Brett Dennen, Gavin Degraw, Grouplove,
Two Door Cinema Club, Bon Iver, Ron Pope (recent new EP called "Monster" on itunes. I'm biased because I love him but I think it's awesome),
Five Times August, Matthew Mayfield, Sia, Suzanne Vega, Kate Miller-Heidke, Phillip Phillips, Ellie Goulding, O Monsters and Men, Two Door Cinema Club,
The Gaslight Anthem (Rock music), Adam Pascal (Rockish music), Tyler Hilton, Fiona Apple, Norah Jones, Lana Del Rey, Keane, Passion Pit if you like some electronic stuff, Local Natives, The Civil Wars if you like The Lumineers or Phillip Phillips, Oceanship, and David Cook
I also second Foster The People, Anberlin, Paramore, Hit The Lights, Yellowcard, Imagine Dragons, Owl City, The Lumineers, Snow Patrol (except their newest album), You Met At Six, Chase Coy, Demi Lovato, and Lights
You probably heard of most of those though…If not, great.
FOSTER THE PEOPLE Pumped Up Kicks, Houdini, Call it What You Want, any song by FTP is brill. Youth - Daughter. I'm listening to it now, it's just beautiful.
You Me At Six, Chase Coy, Demi Lovato, LIGHTS, ahhh. I can't think of anymore bands because all of the ones I can think of are the ones you've already named. :p
If you like indie music, you may like Foster The People and The Presets. Calvin Harris is also good, if you like popular music, as is Owl Eyes if you like beautiful things.
*Sorry if I repeat something you already stated* okay. here goes nothing. 100 in a 55 by pop evil, All Eyes- Imagine Dragons, Bad-The Cab, Bluebird- Christina Perri, Chasing Cars-Snow patrol, Chemicals- Breathe Caroline. And a million more!
30 seconds to mars, afi, Anberlin (amazing), Yellowcard, Capital Lights, Thousand Foot krutch, Skillet, Hit the Lights, Red Jumpsuit Apparatus, Pierce the Veil, and Mayday Parade
AWOLNation, Rob Zombie, Puffy Ami Yumi, Girls' Generation, Paramore, and Angelspit are some amazing artists. Puffy Ami Yumi is a Japanese duo and GG is a Korean group of all girls. ^_^
