Love this App but...

Really love the idea of this app but unfortunately I am having a hardest time downloading the music. It crashes a lot, takes a considerable amount of time or just doesn’t download. But once it does, its fun to play along with the quartets or duets and change the tempo, viewing, etc. Very cool idea..unfortunately cannot take the length of time to download. Won’t be renewing.
