Not for intermediate players, DEFINITELY not for beginners.

Few important points I wanna make:
-The chords written are not accurate to what is being played. The developer confuses major/minor/dominant chords. So basically everything. Measures and song forms are written very poorly. Good luck figuring it out on your own.
-Tracks don’t sound authentic to any of the styles available. I mean not even single one. I understand if the developer is a metalhead not familiar with jazz music, but the person is an amateur musician who really needs to study more music.
-Basically it’s just a guitar player playing poorly made riffs over drum machines. And even the guitar tones sound really cheap.

If you’re a serious musician you will immediately figure out that you’ve made a mistake by paying high dollars.
If you’re a beginner, only thing you will get out of this app will be a bad habit of misreading music.

I’m seriously ashamed of spending money on this app. I could’ve made a better library of jam tracks on my own in a single day.
Sorry developers. Hope you made enough money to go take some music lessons.
