How do you search radio stations?

Question

In iTunes 10, I had a playlist called "All Radio Stations". I created it by opening a genre under the radio heading (i.e. Adult Contemporary, Alternative Rock, etc.), copying every radio station in that genre, and pasting it into my "All Radio Stations" folder. I did that with every genre, until I had every radio station accounted for in my playlist. Then, I could search for a particular station by name rather than trying to guess which genre it might be listed under. Then, I created a couple smaller playlists with my favorite radio stations.
Then, I updated to iTunes 11 which, surprisingly, created albums (each listed as "unknown album") of my radio station playlists. I don't want these radio station playlists to be treated as albums for 3 reasons: (1) they are not albums; (2) it causes iTunes to hang for up to a minute when I select one under album view; and (3) I don't want it to be included when shuffling all songs or albums.
Is there a better way, perhaps a script, that allows one to search for radio stations by name?
Is there a way to create a playlist of radio stations without iTunes automatically turning it into an album?
Why didn't Apple make it possible to search for radio stations on iTunes by their call letters?

Answer 1

After a little experimentation, I have discovered that creating a playlist of radio stations causes an "unknown album" to be created, and any additional playlists of radio stations that you create are then automatically added to that "unknown album", as if they were songs on that album. Radio station playlists are not albums, and should not be represented as such.
Also, I would still like to be able to search for radio stations on iTunes, whether by call letters, name of the station, or perhaps by words included in the description of the station. Apple lets you search like this is your playlists, albums, songs, podcasts, movies, etc. this way, but not radio stations.
