If you've listened to San Francisco's KVVF 105.7 in the past 24 hours or so, you've been treated to exactly one song: Nelly's "Hot in Herre." It's been playing on loop since 3 pm yesterday, Rolling Stone reports. At first, no one was quite sure why, but RadioInsight explained the situation: The station is getting a relaunch. Instead of Latino Mix 105.7, it will now be Hot 105.7, an English-language station. Twitter has, of course, been amused, discussing the phenomenon using #Nelly1057. It's not the first time a station has tried what's known as "stunting" during an overhaul: Toronto's new Indie88, for instance, last year played only Rick Astley's "Never Gonna Give You Up" for a week, Rolling Stone notes.
