It's fine as a free novelty to play with friends before or after a session of BR but the monetization structure here of buyable songs is expected but really terrible, especially given how middling the actual gameplay is here. Takes almost no time to get 98%+ scores on expert drums level due to how loose the timing is--again, it's fine for a free novelty but no way in hell am I paying 500 god damn V-Bucks for Party Rock Anthem, that's fuckin' highway robbery.
