I love Of Monsters and Men, Rise Against, Switchfoot, Underoath and Paramore. I've heard a lot of good about Imagine Dragon and August Burns Red
Well, for me, it couldn't be more broad. I love older stuff such as Johnny Cash, Bob Dylan, Bon Jovi, the Stones, Tom Petty, Sinatra, Phil Collins, Stevie Wonder, Aerosmith, etc.
I also like Country too. Blake Shelton, Little Big Town, Miranda Lambert, Toby Keith, Keith Urban, etc.
I like Indie, pop, rock, electronica, some rap (the kind that isn't all swag and hoes) and alternative.
Some of the more recent non-country artists I like are OneRepublic, John Mayer, The Script, Marianas Trench, The Daylights, Breaking Benjamin, 3 Doors Down, The Fray, Fun, Lifehouse, Linkin Park (their older stuff), lostprophets, Fort Minor, Red Jumpsuit Apparatus, Trapt, Coldplay, Orianthi, Story of the Year, Macklemore, Jason Derulo, and Three Days Grace (their older stuff)
I have a lot more....it's just that the list gets really long. There's really no pattern in the music I listen to, either.
