Can't edit song details iTunes 12.2
Hello, since downloading iTunes 12.2 today I can no longer edit the details for some of my songs. I have checked that the files are not locked and that they are not read only. Before the update, I could edit song details for every file in my library. Any suggestions how I can fix this guys? I'm running the latest version of iTunes and the latest version of OS X Yosemite.
Thanks
