Ahhh, the intense pain of unrequited love! We've all been there at some point, even Taylor Swift.
REO Speedwagon, "Can't Fight This Feeling"
This has been the anthem of milquetoast dudes with a crush on their best friend since long before anyone ever coined the term "friend zone."

Biz Markie, "Just A Friend"
Biz's off-key warbling only make this song about being rejected that much more affecting. It's a funny song, but he really makes you feel his pain too.

Pulp, "Like A Friend"
Jarvis Cocker has a few songs from within the zone, but this one is the best because it taps into some serious frustration directed at both himself and this woman who keeps stringing him along.

Bonnie Raitt, "Something To Talk About"
This one is kinda arguable! It's basically Bonnie addressing rumors that she and this guy are a secret couple, and being like "oh, let's just for it!" So you can either look this optimistically and see it as the beginning of a romance, or be a pessimist and see it as the first step into a friend zone in which she just sings "I Can't Make You Love Me" over and over and over and over.
