When you listen to a radio station and like it enough to Follow it, you should be able to see these Followed Stations on the Radio homepage, because this is the section you'd navigate to in order to find stations again. Right now the Radio homepage has swimlanes for 'Recently Played' (- by others, not you), 'Recommended Stations' and 'Genres'... but there should also be a lane with 'Your Followed Stations' so you can listen to the stations you like regularly without searching.
What's the point in Following a Station if you can't find it? If they're only listed in the long list of Followed artists, it's hard to find them in there and that's outside of the Radio section.
