When I downloaded this game, I felt like it was a great throwback to the days of rockband/Guitar Hero. When I realized that boxes with new songs had to be unlocked over time, I had a bad feeling. When those slots become full, the game becomes unplayable (literally, you can't even play a song while your box is unlocking). It's a clear money grab via micro transactions, and I can't recommend it for that reason. I would have gladly paid a few $ for the base game plus occasional expansions.
