Some are related I guess. For example Starships always reminds me of Trek because I once rewrote it as a Trek parody (I am quite proud of it if I do say so myself
) as well as E.T by Katy Perry (just imagine Spock listening to that song and the face he would pull XD) Blue Skies is an obvious one as well (makes me cry every time I hear it) as well as Come Fly With Me.
Cold Shouler by Adele (Reminds me of Bashir and Garak
You've Got The Love by Florence and the Machine
Home by Edward Sharpe and The Magnetic Zeroes
Demons by Imagine Dragons
