I can't play files converted from AIFF-C to mp3 in iTunes
I've converted an old AIFF file in Audacity to mp3 but can't drag it into iTunes (12.2.2.25) or open it in iTunes.
Mac mini, OS X Mavericks (10.9.5)
Does it play in Quicktime Player? Is it even a valid file?
In iTunes are you checking the Recently Added playlist? Converted files may not arrive with labels and will not end up where you expect them to.
