You guys are taking this playlist way to literal. Don't forget that artists get credit for streamed songs... This is just another avenue for Jon to promote and get some more plays...

He puts together his greatest hits, throws in a Bon Jovi song for every other song, shares his playlist on social media, and bang, his numbers go up...

Without even looking, I bet 90% of those artists are on the same record label (especially the current ones)...
