Here at Channel 4 we use the sung cuts as well as the sweepers to segue between songs. Coming out of stopsets we tend to use the shotguns that are part of our package. Although we have the Reelworld ramps, we don’t use them that much.
There are also positioners that are used to segue. These are 30 secs in duration & include grabs from some of the new music that we play, for example – http://s11.yousendit.com/d.aspx?id=7D24FB81B7F9A56B65EEEE44E74584BE
If a station ends on a promo that is tagged with the station name, then they go straight to the next song, no jingle needed.
The way it’s done in the UK and the US is pretty much what you mentioned. Z100 New York use ‘image kickers’ to get them out of stopsets.
