Otherside - Red Hot Chili Peppers

think up, bring up, go back, turn on, tear down,

This song features on Californication, RHCPs most successful album, and was released as a single in 2000. Most writers seem to agree that the song is about fighting drug addiction, specifically heroin, and or suicide. RHCPs founder member,  Hilliel Slovak had died in 1988 and some fans regard the whole Californication album as a tribute to him.

I heard your voice through a photograph
I thought it up, it brought up the past
Once you know you can never go back
I've got to take it on the otherside

Turn me on, take me for a hard ride
Burn me out, leave me on the otherside
I yell and tell it that it's not my friend
I tear it down, I tear it down
And then it's born again
(Otherside - Red Hot Chili Peppers)
