Good app but needs improvements

I paid the $1.99 for the app and at first it was really hard to understand then I finally figured it out . After about using for about a week I realized the sound quality is coming out of the app is terrible. All my songs are bought from Apple they are all good quality but when they are played thru this app they get crackly and dont have as much bass.
