Ooo ~
If you want something new to listen to, I have a few suggestions you can try c:
Beautiful Times - Owl City With Lindsey Sterling. I just find this song beautiful and one of my all time favorite as of now.
Lindsey Sterling She is....my role model along with WhoIsDSharp(?) I think that's what he goes by, when it comes to instrumental, violin styled songs. DSharp did some really cool songs and Lindsey did songs for like.... Zelda, Pokemon, etc. and it's worth checking out.
Maroon 5 & Coldplay when it comes to their songs like Animals ( Maroon 5 ) Or Paradise ( Coldplay ) and such.
Again, these are some suggestions that I can think of since I listen to a lot of music and I'm definitely sure that there are others out there ~!
Thanks! They are both amazing! Also, I listen them in my little telephone (No joke, it is very small). So that's why.
Icon For Hire and Any Given Day. Both of these are metal/rock (IconForHire being the rock) but they both send out important messages to the world that not many do. 
I am pretty sure Icon For Hire is small, but Any Given Day I'm unsure of. 
Icon for hire <3 I know it but I only listened to her one song: I'm sorry about your parents and it was really good. Thanks!
Well since you like Portal there is a channel called Harry101uk https://www.youtube.com/user/Harry101UK/videos and he makes songs about the game.
Also you can look at this channel https://www.youtube.com/user/TheSamTsui/videos he is a really good singer, and makes lot of music videos.
Yeah, I know Harry101UK's songs and the carol of the turrets is my fav. Thanks anyway!
Well there is DNCE who sing Cake by the Ocean...very fun song.
There is always Creature Feature if you like weird stuff.
Steampunk Giraffe is fun too.
If you like mellow try some folksy tuns by searching things like Mumford and sons, that will lead you to some interesting things.
Musical stuff like Lindsey Stirling is always good too.
Yaas, I saw cake by the ocean in the TV music programs, but I suppose DNCE has good songs.
And yeah, I checked Lindsey then it was so acceptable.
Everything Everything and Marina and the Diamonds are both AMAZING.
There's also Mariana's Trench and Imagine Dragons. These are just a few that could relate to the genre to a degree.
I've also got a lot o' Indie and Metal suggestions too, but they might not be your style.
I'd still recommend Lord Huron though, even though it's more Indie style. Any one of their songs can be almost like an epic RPG or book/movie.
TRUE, I am a fan of marina too (if you are ;-;), and I like these india styles much more. Thanks!
Thank you all! +Nuzzle to all.
Now I see, other's song ideas helps other people too.
