Ever drive around listening to the radio and you hear a song that you like but don't know the name of it? Maybe you know the name but don't know the artist. How will you ever be able to find it on iTunes? Never fear! Just use Yes. Load the site on your home PC (mobile browsers work pretty decent too) and in the search box at the top of the page, type in the station call letters and or the numeric dial location and then hit the YES button. So let's say you are in the car and you just heard a kick ass song. Make note of the time and then when you have access to the internets, hit up Yes and search for the call letters of the station. It will list all the songs played going back 7 days ordered by the time of day it was played.
Holy craps!! It' da bomb! Any other services like this that may be better ... Let me know.
