One of the lamest 80s power ballads is undoubtedly When Its Love by Van Halen. I mean come on, if you can’t answer the questions, don’t write a song about them!
I love how the band sings the questions to Sammy, he replies with his lame answers:

Band: How do I know when it’s love?
Sammy: I can’t tell you but it lasts forever
Band: How does feel when it’s love?
Sammy: It’s just something you feel together

Duh. I still think Van Halen is great, love a lot of their music, but that song will always annoy me, and possibly you now too.
