I was just using the audio browser for searching for a radio station (BBC radio 4). I was doing this, because the search feature did not let me (error message).
I think that the audio browser could be improved in two ways.
a) there should be a refine feature that lets you refine your search by either language, genre, location, popularity ... . I know that you can sort, but in some cases you still need to go through many pages of stations, before you find what you are looking for.
b) I think you should allow more stations to be displayed than just 10. That would speed up browsing considerably
