The features that I like most are being able to have different types of genres, such as country or pop which you can then create your own station out off those two stations with certain artists in mind! They also allow me flexibility when it comes down creating my personal playlist because they give options depending what type song i want (dance/pop vs rap).
Sometimes there is no option given unless its just an artist but other times if something isn't available at first glance maybe try again later? Try them all so see whats best suited for yourself!! We've been using overhead radio since 2015 now we're still going strong everyday listening over our car speakers while driving around town doing errands etc.. It allows us freedom during work time by not having worry about playing songs constantly throughout lunch breaks ect...
