Pandora - a channel I seeded a year or so back with some Monk - straight out from my Lenovo T420 running Ubuntu 16.04 LTS. I use Pithos, a labor of love Pandora player available for Linux. It's like the Pandora apps for Windows/OS X that use Adobe Air, except this doesn't use Air. it's small, neat, a little joy.
So far tonight, the algorithms have pitched Monk, Lee Morgan, Blue Mitchell, Coleman Hawkins, more Monk at me.
My habit lately has been to just plug in the Grado SR80s - no DAC, no amp, no nuthin.' Somehow, I like them better like this.
