I don’t think there is anything wrong with the song that you are currently using. I like the song but I think that a new intro, maybe about the show, would be an improvement.
The Wednesday song was cool for the first season because it let viewers know when to expect the show but now you have gained a lot of interest and attention. I found that when I would recommend my friends watch the show sometimes I couldn’t even remember the name of it. I just called it the Wednesday show.
Aside from relating the intro to the show, or the name of the show rather than the day that you post it, I think it would be fun to have a fresh new intro.
