It wasn't eligible to chart on the Hot 100 at first because it didn't have a commercial single release. It did peak at #2 in both the UK and Australia charts though!
Then in 2005 it went #1 on Hot Digital Songs, but it couldn't enter the Hot 100 because it was a "recurrent single"
But now that recurrent singles can re-enter (above #50), the song's been "peaking" for the last few years. It's doing pretty well this year already, so it may got top 20 finally!
