I just wanna say that I absolutely LOVE Garbage, and I adore both of their albums.
However, this single was just totally disappointing. When I Grow Up is a great song, but it's the only great song on the single. "Tornado" is seriously the worst Garbage song I have ever heard. I didn't think it was possible to write a bad Garbage song. The "Special" remix didn't do anything for me either, it bored me after a while.
Only get this single if you collect Garbage stuff, because unless you are a MEGA fan, it's just not worth it, and you're better off buying the "Special" single so that you can hear a REAL Garbage B-Side.
