Songs like................fix you (coldplay) and how to save a life (the fray) also chasing cars (snow patrol)?

Another calm meaningful one is the acoustic version of Everlong by the Foo Fighters, it's really beautiful. Hey There Delilah by Plain White T's is also good :) And the live acoustic version of The Kill by 30 Seconds to Mars <3 Don't know if that's the kind of thing you meant, but to me they have great meanings, and are just calm, gentle songs :)
