Good gameplay made impossible to enjoy by aggressive monetization. It's fun and looks great. The song selection is among the best I've seen. But barely any freemium currency given out, and the game's flow is constantly interrupted by demands to spend a little in order to continue. Lootboxes are the main progression and can be earned through playing but take hours to unlock. Have too many? Well, gaining 0 progress isn't bad enough. You can't play anymore until they've unlocked. Embarrassing.
