What qualities do you look for in a pop star?

[katstevens.livejournal.com]

Obviously musical/singing ability is required (well, most of the time) but what else?

- Eccentricity?
- Frivolousness?
- Dancing ability?
- Number of white towels in their rider?
- Appearing on Saturday morning kids' telly/Christmas specials?

Phrasing the question slightly differently: What makes you think an artist is 'pop'?
