In 1.0.4 we added some pretty robust crash analytics to Hum. We’ve had a few growing pains that have come in the form of crashers, but we’re working really hard to get some fixes out the door.
Today we’ve released 1.0.5, which fixes a number of crashes stemming from the same bug. When you put Hum in the background while working on a song, Hum could lose track of if a song existed or not and cause a crash. Frustrating.
It should be fixed now. Have a look at our release notes.
