I second He Is We!!! :)) One of my faves would probably be Happily Ever After. Also Prove You Wrong.
-TSwift. Though when I say TSwift, I mean her slightly less known songs. For some reason, her new and really famous songs are 'not quite my tempo' so I totally recommend How You Get the Girl, I Wish You Would, Clean and Your Are in Love for her latest album. But going back a bit, my all-time fave is Fearless, next comes The Last Time ft. Gary Lightbody of Snow Patrol. But some other few would be: Ronan ( :'( ), Last Kiss, Ours, Long Live, Back to December, Today Was a Fairytale, Invisible, and Fifteen. Yep. Imma shut up about TSwift before I start saying a lot of titles.
-Owl City yessssshhhhhhhhhh aaaaaaahhhhhhh *melts* :DDD *hums Strawberry Avalanche*
-The Lumineers. A friend of mine recommended this trio to me and their songs are beautiful, and relatable as well. Recommending: Submarines, Ho Hey. :)))
-Seafret. I have heard one of their songs a while back. This was Oceans, which featured Maisie Williams in the music video. But it was only recently (during a great time of crisis in the academic side of my life), that I seriously listened to their songs. All time favorites are Wildfire and Did We Miss the Morning. Oceans, Atlantis and Give Me Something follow behind. And a couple more.
-Birdy. BIIIIIIIIRRRDDDYYYYYYYYY. Her voice is beautiful, her music, heartfelt, her piano, divine. Now, you may find a few of her songs not to your taste (she underwent a phase of change between her three albums), but yeah, she is great. Maybe you're familiar with her if you've watched Brave, TFIOS or Winter's Tale's trailer where she sang Learn Me Right, Not About Angels and Tee Shirt, and Wings, respectively. Recommended Songs: Wings, Start Again, Not About Angels, Standing In The Way of The Light, Skinny Love, Words, Deep End. Yep Yep.
-The Script. I. LOVE. THESE. GUYS. Honestly. So some songs areeeee: The Man Who Can't Be Moved *starts humming,* Never Seen Anything (Quite Like You), Man on a Wire, This=love, If You Ever Come Back, Walk Away, No Good In Goodbye.
-One Republic. (We actually have no internet connection while I'm writing this, so I;m just gonna write stuff more and more) SECREEEETS!!! Have you watched The Sorcerer's Apprentice? The one with Nicholas Cage and Jay Baruchel, yeah that. Secrets was one of the songs playing there. Yep yep. Can't remember which scene though. Anyhow yeah. Also: I Lived, Au Revoir, If I Lose Myself and Preacher.
So yep. *goes back to rewatching Tokyo Ghoul while waiting for internet* I'd give a few more names, sadly their songs aren't english anymore.
