Hugely fun and entertaining and the core music packs are good, but if they're not your style there are tons of DLC from popular artists and even tons more free custom songs made by fans. If you enjoyed Guitar Hero or Rock Band you will likely love this. I was always quickly bored during cardio exercise but now I try to play Beat Saber every day for an hour or so and it burns about 600 estimated calories and it's great fun. My current skill level on YouTube. I also recommend getting it on the PC, as well as the YUR fitness tracker on Steam(free). Lots of modding available as well.
