Spirit: Riding Free All End Credit Versions

I couldn't include the spin-off versions the show because I think in each episode has a different theme music in the end credits and tried make the video under 10 minutes so that's why they were left out. So, I first started watching this series back in January and have to say that show pretty good in my opinion, the theme song in show sounds pretty catchy to me, like I would listen to it all time. But I don't know why they ended the show for some reason since it been almost 5 years since the last season of Riding Academy spin-off.
