Replying to can you name this classic rock song?

It's killing me. I heard this song the other day and I thought it was pretty bad ass, unfortunately I have no idea who sang it or what it was. If you're able to help me out, I will love you forever.

So far, this is what I can remember.. It's a classic rock song, lead singer reminds me of jimmy hendrix/lenny kravitz. and the chorus goes..
CHANGE! and the world starts.. ( I have no idea)
UNCHANGE! .....

I know. it's vague.
