Ok, so I'm trying to upload a song that I recorded on Garageband onto my profile at Ultimate Guitar. It apparently needs to be an mp3 file so I'm trying to convert my song file. However its strange... I have not messed with the song files since I recorded them yet one of my songs is able to be uploaded without any file conversion... Unfortunately it's not the song I want. The song I want, along with two other ones, are greyed out and unable to be selected. And I'm using a downloaded program called Switch and it's the same deal there, three songs, including the one I wish to select, are greyed out while the other one is able to be selected for file conversion. What's going on here? Also I can't figure out what type of files they are to begin with... I'm looking through all the file info and I can't seem to find the answer anywhere. Someone, help!
