Yammat FM is a Croatian radio station known for alternative and popular music programming, and Petak is the Croatian word for Friday. Short idents like this are produced for broadcast use, naming the station and the day in a few seconds so listeners instantly know what they are tuned to. Clips of radio jingles are often lifted from broadcasts and shared on soundboards, where they take on a second life as markers, transitions and in jokes. This one remains popular for signalling Friday and the start of the weekend.
