Weren't you one of the people praising LoEG: Century to the skies?
In the case of Top 10, the songs work for me because the whole series is supposed to be a TV police drama series filtered through the lens of superheroes. I read the songs as his attempt to mimic the musical montages that TV shows, cop shows included, do. Their inclusion emphasizes the similarity to the source material, the same way the "End of Season One" line does.
