In Sweden, we call this music genre schlager and we take it very seriously, indeed.
So much so, in fact, that we like sending it to the Eurovision Song Contest to represent us (with generally rather adequate results, if you don't mind my saying so...).
I'm not sure what this British band calls it - probably not a Swedish word... 'disco' perhaps?
Whatever the term, the music is perfectly well-suited to the middle-aged runner I am.
If you are under 40, you probably want to steer clear of this.
