Update: I think I've figured this out. For whatever reason, Tycho (tychomusic.com) has two songs on Pandora, 'The Daydream' and 'The Disconnect'. Problem is, they're listed under Tycho Brahe (www.tycho.com.au). And Tycho doesn't even have a profile. Head to Tycho (tychomusic.com) select 'music', and you'll see the complete Tycho Discography. Also, here's Tycho Brahe's discography.
I use Pandora religiously. Everywhere. I'm also obsessed with Tycho Music. This is the fruit of 1.5 years of hoping Tycho Music would wind up on Pandora. Wanna help? Just post something on twitter with #tychomusic in the tweet. It will show up below. Want to keep track of this project? subscribe to the RSS Feed
Also if you haven't heard Tycho Music, here's an iTunes link.
