What's that sound?

So if you had a chance to go to Sebastian's myspace and take a listen than you heard 3 new Timbo tracks. So did anything sound oddly familiar? Take a listen to Tawanna's "Tonite" and Shelby Norman's "U Hated Me" again. Can you hear it?

Hear that strange "bink bink bink" at the beginning of both tracks? Well that sound has been on a number of Timbaland tracks throughout the years. Ironically, or maybe not so, the tracks it appears on are either unreleased or a snippet. More than likely though, this sound appears on unmastered Timbo tracks. For example the sound appears on:

Aaliyah's "Time"
Attitude "All By Myself" (snippet)
The Kevin Garnett Commercial track
Pooda Brown's "Test My Boyz" (snippet) though the vinyl does exist and I have a feeling this sound has been omitted
and the 2 before mentioned tracks.

So what exactly is the sound? Well I think it's a sort of electronic metronome. What makes me say that? Take a look at this video:



Hear it at the end?

So what do you think? Is it a metronome? A music cue? Ahh the mystery....
