The Music Quiz

Please guess the song and artist from the lyrics. 

No internet usage please.

I'm hoping that we may get different generations join in.

If no-one gets it, then just post a new one.

You're watching yourself but you're too unfair

You got your head all tangled up but if i could only

Make you care

No matter what or who you've been

No matter when or where you've seen

All the knives seem to lacerate your brain

I've had my share, I'll help you with the pain

You're not alone
