My most famous song?  "Tah-Takka-Takka-Tahhh-Takka-Takka."  Without a doubt.  I'm sure you've heard it.  It was written for programmable rhythm machine and synthesizer.  That's pretty much the entire song:  "Tah-Takka-Takka-Tahhh-Takka-Takka."  There's a shift in the key signature, add in a little "twaddle-lee-dah" with the synthesizer, and then it repeats.  Forever.  You know, composing music for people on hold may not be glamourous, but that song there, "Tah-Takka-Takka-Tahhh-Takka-Takka," it's been heard by more people on the planet than any other song.  Ever.  The Beatles.  Elvis.  Bob Marley – they can't say that.  But I can.
