The current Google Doodle, a fully functioning web-based synthesizer in tribute to the late Robert Moog, prominently features a record button. Hundreds of cover songs are being recorded by users around the world using the Moog doodle.

Here's a sampling of some of the best – and geekiest – cover tunes recorded with the Moog Google Doodle, as seen Wednesday on YouTube.

Daft Punk's 'Aerodynamic' by Brett Domino —————————————–

The clear winner, so far, is the inspired cover above of Daft Punk's "Aerodynamic" by Brett Domino. The video, too, is inspired, with multiple simultaneous shots of Domino raging at the keyboard, rushing to re-create the song's uber-fast synth line in real time.

Legend of Zelda Medley ————————

Several users are recording cover versions of various Zelda theme songs, with many focusing on Ocarina of Time. But this complex medley, as judged by Wired's resident Zelda expert Amy Zimmerman, takes the prize.

'Jump' by Van Halen ——————-

The triumphant opening strains of "Jump" by Van Halen are captured masterfully in this Google Moog Doodle rendition by Aaron Isles.

The Doctor Who Theme ———————-

The Doctor Who theme, a stone-cold electronic music classic, has been the subject of several Google doodlers. This tribute, uploaded by YouTube user Mel Adroit, stumbles a bit in its rendition, but it gets an A for effort.

'I Feel Love' by Donna Summer —————————–

The late Donna Summer, who died last week, gets this brief tribute, also by Aaron Isles. It's a good start, but someone should try for a longer version.

'Bad Romance' by Lady Gaga ————————–

Lady Gaga has been a popular muse for many Google Moog Doodle users. This take on "Bad Romance," created by YouTube user DarkerThenDarkness, was the best of the many renditions of the song we heard.

Phantom of the Opera Theme —————————-

The Phantom of the Opera. What more needs to be said?

The Mortal Kombat Theme ————————-

Mortal Kombat got several tributes today – someone has yet to create the definitive version, but this will do for now.
