I've split the three different screens into different "genres" I guess you'd say. On SAT1 I have music: Top 20 on 20, Kiss 21, Mix 22, Cinemagic, U-Pop (Worldwide hits) and some random Latin one #94 that I blast with the windows down on occasional humorous nights out

'
I barely use SAT2, but that's where I put the "talk" stations with comedy, etc.
SAT3 is news. FOX, CNN, ABC, C-Span and I think MSNBC & CNBC. Close enough, anyway

Works great.
