With the advent of Electronic music, it's much easier to copy sounds - a simple cut and paste and you'll have exactly the same music as someone else, but which sounds have been copied and pasted the most? Which sounds have people overused to the point where they've become intrinsic to the popular music industry?
Let's find out...

808 Kick - Often backing up the Amen break, the 808 kick began its roots in a humble drum machine and has now spread the world over as one of the most used kick drums ever. Hip Hop thanks you, 808!
TB 303 Synth - Fast sequenced resonant synths were the order of the day when acid house and trance kicked off, with the TB 303 being the chef.
Supersaw - Could you imagine conventional music without the massive anthemic trance leads of the 90s being punctuated throughout it? It'd be like losing a limb! With an awesome name as well, the supersaw synth is vital to the dance music industry!

Gated Snare - Thanks to the 80s, these reverby monsters of snare drums have been the driving backbone to many a Rock and Pop anthem.
Percussive Blip - Yeah, I'm looking at you, Timbaland. Those early drum machine blips have become such a staple in hip hop that you'd think they weren't pitched samples at all.
Reese Bass - Kevin Maurice Saunderson has shaped modern Drum and Bass forever with his dirty, powerful bass synth.

Vocoder - Would daft punk even exist without this? Pioneered by Bob Moog, Kraftwerk and others, used so much in pop music it almost hurts.
The Big Beat - Another one of those samples that pops up again and again - Run DMC, Naughty By Nature, Jay-Z and Dizzee Rascal have all spat over the top of this loop. Whether you think of spitting as a synonym for rap or a derogatory thing is up to you!
