There are a few possibilities for "spun up":
- "entangled/trapped", as in a spider spinning a web around a fly.
- "promoted on radio", as Nique explained. Extra "spins" for extra exposure. The song is moved to "high rotation" (ie. played often).
- "elaborated with false or exaggerated details", as in "spin-doctoring". To "put a spin on a story" means to find a tiny angle of the story and exaggerate that. Sometimes the actual truth of the story is lost in "the spin", so this is considered a form of lying. People who do this profesionally (ie. reinterpret the truth to fit someone's agenda) are called "spin doctors".
