I did not know this. I used to try to use iTunes once a year for a test to see if it would crash or fail to import my music, and it always crashed after a few hundred thousand songs, then I think i tried it a final time a final year with nearly a million songs, which is not actually a lot, and it failed. So I never again tried to use Apple iTunes on mac nor windows for anything , ever. Its a toy for people with small music collections. Apple in the news, once, put a limit of 25,000 free up-conversions , so Apple considers 25,000 to be excessive I guess. Upconversions are when apple takes your 128 kbps 32 frequency bin MP3 files, and graciously deletes them and replaces them with better non-drm MP4 files using 48 frequency bins and better stereo, but if the song was uncensored version of rap music... Apple deletes it and replaces it with "radio friendly" censored version without your consent... forever. (I am not kidding, do a news search). iTunes can go fuck itself. Apple did not even write iTunes. They bought it from "Sound Jam" and just renamed it. **ITunes song limit in 2018 is a pitiful 100,000 maximum!:** ========= https://discussions.apple.com/thread/7896042 bwah hah hah hah hah!! I had over a million DECADES ago, and iTunes still cannot even list 100,000!!!! comical!
