No longer can import mp3 files I create for myself (no copyright issue)
For years I have added small mp3 files to iTunes. I use these for musical ear training. Last time I did this was in 2024. Just now however, adding these mp3 files doesn't seem to be working. I have seen several threads on mp3 import issues, but nothing that seems to help me accomplish what I want. Can someone help me out? Has something changed? I believe these are fairly vanilla mp3 files.
