I usually buy songs on my iPhone, and when I open up my computer, they're automatically in iTunes already. I bought three songs last night and went to listen to them on iTunes today and they have an exclamation point next to them.
When I click on the exclamation point, nothing happens. I've had these exclamation points before when I've accidently deleted the file from my computer. But it's never happened with my iPhone before. I even went to the Purchased tab, and hit "download previous purchases", but it says the songs are already downloaded and won't let me re-download them. I have no idea why...
