This is, of course, a very subjective question. One of the biggest hits by a true one-hit wonder was "In the Year 2525" by Zager & Evans back in 1969. It stayed at #1 for 6 weeks and they never hit the singles chart again.

The answer is "I believe in miracles" by Hot Chocolate. I'm sorry, "best" is subjective. You'll have to be a little more specific in what you mean by best.
