I have to admit that occassionally (to relax during and after work, not to be intellectually stimulated) I am watching german, french and sometimes british or croatian tabloid and realitv shows and I can say that recently ESC saw an increase of mainstream songs that became part of a massive canon used by these editors as tacky background music.
Only from the last few years, Grab the Moment, CityLights, (I'm not your) Toy, Fuego, Lie to Me and even Amor pelos dois I hear from time to time while watching a show where they want to underline and emotion by a song which is saying excatly that. If there would be a scene where someone would surprise their mother "Hey Mamma" could be played for example
I see this as a factor in how ESC is much more a mainstream thing now again than it was 10 years ago.
