Some music not accessible
In my iTunes, some of my songs have an exclamation mark beside them and this is the message I get when I click on it:
The song “All I Wanna Do” could not be used because the original file could not be found. Would you like to locate it?
When I click yes, I get a long list of music that I don't recognize. Can you help me?
iMac, macOS Sierra (10.12.4)
