The ones that I can think of off the top of my head are...
ANGEL'S SONG and fairyland
When I first heard fairyland, ANGEL'S SONG wouldn't get out my head.
(don't) Leave me alone and identity
Same key, I believe? And that stuff before the chorus in each song... You all know what part I'm talking about.
And there was another song I connected with criminal the other day, because I thought they both had a "haunting" feeling. But I absolutely cannot remember what song I associated it with! ><
Oh, I used to always mix up the lines of Boys & Girls, Trauma, and maybe even flower garden together. X3
