Haha! Metronome is the most amazing gamble ever! While younger, Togepi was my favorite pokemon, and I would usually keep metronome as my star attack. I got EXTREMELY lucky. Whenever Togepi's health was low, it would be a healing attack or a blow up attack. I didn't like the exploding everywhere, but healing was fine. Other than that, it was mostly Sp. Atk moves, with the occassional random/no help move.
My 2nd Togepi in a diff. game was unremarkable and I had horrid luck with Metronome in general, so I replaced it.
In Platinum, I had the luckiest Metronome all the way until it evolved into Togekiss. Serisously. I called it m physical Togepi! Haha. First time using it, it scored Sared Fire. Haha. And subsequent violent, strong attacks. <3'd that Togepi. It seemed to know the exact attack to do. It scored mulitple super effective's. I was super happy. But then...it evolved into Togekiss and all my luck turned. Then it started doing stupid attacks like light screen. -_-
But...Metronome is still an amazingly fun attack to use. Haha
