I have been playing since launch, but because of when I am able to play and my work schedule, I am not able to be on during any of the time that the adventure islands are available.
So because I can not do the islands I can not get the some songs to complete some quest, as well as I will not be able to get any of the island tokens from them.
It is very frustrating knowing that I will probably never get these things done due to my schedule.
