The videos are not too exciting to listen to… they are educational tools! (It’s also good to know that the speed of cheers at the stadium are about 1.5 times the speed that they are in the videos. You can set the speed of the videos accordingly if you want to practice them at actual speed!)
You can also practice “karaoke” versions of the songs… you can find them all on the official YouTube channel of the Cheer Song Association. Look for videos with the word カラオケ版 in the title.
