Unpredictable. Unfocused. Just like life.

A cell phone ringtone based on the sound of a revving Swedish mo-ped is going to keep Coldplay out of the number one spot on the British singles chart, outselling the band four to one:

"Crazy Frog Axel F," a ring tone based on the sound of a revving Swedish mo-ped, is the first tune being used on mobile phones to cross into mainstream music charts, said Gennaro Castaldo, a spokesman for HMV, the British music retailing chain.

Coldplay had hoped to go straight to No. 1 on this Sunday's British singles chart with its new song, "Speed of Sound." But by Saturday, it appeared that the ring tone - which is available for digital download and as a compact disc single - would prevail, said Castaldo.
