Worthless

Every song I try to put in this app is a DRM protected song. Should’ve bought two king size snickers instead of spending 3 bucks on this app.

Waste of money

Back a few years ago I told everyone about this app, today I still do but for a different reason. The dang app closes every stinking time you choose a new song. I spend more time opening it and finding a the song than I do playing. Very frustrating.

DO NOT BUY!!! DO NOT BUY!!!!!

waste of money. will crash all the time and i have the patience of Job. no stars. developers r aware but obviously have done nothing. if u click the prompt from the free version to the paid version IT WILL NOT WORK. u must first delete the free app and install the paid version and pay for it to crash more than on the free version. great idea, would be immensely musically helpful if it worked and if these developers paid attention to paying customers who have repeatedly told them to fix these two problems on reviews. But yet they continue to develop and request more ideas for additional apps prior to fixing those out there. i would say this a nickel and dime scam (that pockets them 1000’s of dollars) that needs to be investigated by authorities.

Not good

Not sure what DRM is, but prevents me from using this on a majority of my iTunes library. Thankfully, it was only $3 bucks...I do not recommend this.

Useless trash

Absolutely garbage. It’ll let me open the app but once I select a song it takes me back to the home page
