I don't listen to much radio, but when driving in Oxfordshire I generally settle on Jack FM because it focuses on music rather than inane chatter. To my pleasant surprise, we found it here in Banff — the local version, that is.
According to Wikipedia,
JACK FM is the alternative name and on-air brand of 60 radio stations in Canada, the United States, the United Kingdom, and Russia ... The first Jack station was Vancouver's CKLG-FM, which quickly shot to the top of the city's BBM radio ratingsGreat to see a successful idea replicated. All hail Capitalism.
Stations using the "Jack" name are very strictly licensed by SparkNet. There are several terms that the station must agree to, one of them being the fact that disc jockeys are not to be used for at least the first few months of the format
