There is one other point, not related to the quality or the source of the jingles, I get the feeling that jinglecraft is no longer taught. The music is scheduled by a pc (selector….or similar product) and the jingles are just dumped in! when was the last time you heard a transition…be it tempo or texture that actually worked? I know a lot of stations simply rotate jingles on a mini playlist just the same as the “A list” is rotated.
No wonder there are so many sweepers out there.
