Only plays one song, rest wont load

I have the same issue that other reviewers have mentioned: it only plays "Let it Go"---- none of the other songs will load. For $7.99, this app should play more than one song and have all the kinks worked out. Please advertise honestly what this app provides, fix the broken parts, or issue a full refund. Thank you.
