Definitely not Frank Zappa: his brilliant lyrics are way too engaging not to pay them full attention, and they demand the same part of your brain you use for programming.

Except for "Shut Up 'N Play Yer Guitar", "Shut Up 'n Play Yer Guitar Some More", and "Return of the Son of Shut Up 'n Play Yer Guitar". Also "Francesco Zappa"!
