I use the app on tablet in landscape mode. It's nice...but....kind of awkward to navigate. You might redesign the landscape mode a little bit. portrait mode is composed in nice and clean way but this just doesn't translate into landscape. You can't just rotate stuff. On tablets and in landscape you have to treat it more like a open book (two pages left and right)
Have a look on tunein radio app on iOS (not android). they have a very nice navigation for iPad and they solve access to relaven info by sliding left/right
I like the quick access to menu on landscape mode but in fairness I would more consider putting some more relevant info on left or/and right slide menu.
At the end of the day you have to verify whats the 90% of actions you would do on radio app like this. For me it's not searching or access ing settings it's switching between stations I already found and looking on more relevant info if I like what I listen.
What I like:
visual stream representation
volume slider! (It's the only app that has it tight on the radio display screen)
slider menu (nice way to quickly access it)
