Nice. Unfortunately nothing more than just nice.

Why not to explain what do the statistics do before forcing player to spare these 10 points?
Practicing becomes useless at some point stopping most players at certain point (or near it).
Too quick to progress, too quick to master! It's like ultra-short clicker in current state!
Songs statistics doesn't say too much and are hard to manage when there is ton of songs.
I don't see any point in releasing songs exclusively for albums.
Starting statistics are of no importance - after some level-ups the differences are futile.
Nothing to do with $$ when you got over 10K.
When you have many unreleased songs, there are 2 scrolling bars on release screen!
Hugely repetitive.

Nice loops.
Looks neat.
Quite entertaining for first few minutes.

While not my kind of thing, it's still pretty pleasant to listen. The only thing that I find a little disturbing is the fact that vocals seem to be a little oversatied with high frequencies. Repetitiveness of the beat doesn't seem a problem in this one as the vocals kind of fill the gap.
