Cover art for Walls lyrics by All Time Low

Well, when I first heard this song, I thought it was solely about sex. But I listened to it a little bit with earbleed until 0:19.

I realized it was keeping a up close, personal relationship with somebody. More intimate, more emotional. I was scared this would be pop crap.

Song Meaning

It was, I changed my mind.
