whats up with the unlock function? this app seemed cool so when certain features did not function i spent the 2.99$ one time upgrade. this apoeared to let me skip songs etc cool then the app eventually locked up so i deleted and reinstalled. now i dont have the unlocked enhanced functions even though i am able to log in with the account name i set up within the app. so do i have to pay again for these features? if anyone can let me know how to get the exta features i paid for back id appeciate it.
