Earlier this year, Joe Satriani filed suit against Coldplay for using his chord progression & melody from "If I could Fly" in "Viva la Vida" (comparisons here and here). Dr. Desert Flower's iPod played Coldplay's "Politik" while we were taking down the Christmas tree today... and I noticed... 'this sounds just like the incessant chord progression in 28 Days Later and 28 Weeks Later' (aka John Murphy's - In the House In a Heartbeat) , but less ominous and gloomy, when they do montages of deserted streets or while running frantically away from rage infected hordes. IMDb's exhaustive list does not include any mention of Coldplay in the 28 genre.
Perhaps Coldplay just loves to recycle. there are, afterall, a finite number of notes and combinations - granted there are millions of truly unique combinations (16(exp 8) = 4.3 Billion... 8(exp 8) = 16.7 million... 8(exp 8-1) = 2 million, and that's just if they're in a 4/4 time signature). And then there's the loudness and duration of each note...
The human hearing range is 20Hz to 20000Hz. Therefore range is 19980 (humans can't detect 10ths of hertz). Good human hearing can detect from 0.00 to 250.00 (any greater and you're deaf) decibels for short periods of time. So that's 25,000 (for the loudness distinguishing). 25000 * 19980 = 499500000
Planck's time (smallest unit of time) is about 3.3 x 10-44 sec... so that would be about (1.64835 * 10^53)*seconds of duration = number of possible songs.
For 2 second durations, there are a possible:
Hmmm... I am not sure if Coldplay is really "recycling".
