I began using iTunes in 2005 and then subscribed to iTunes Match in 2010. I relied on iTM to manage my music. Since mid-July 2021, I wasted DAYS trying to upload new and previously uploaded music files.
My thinking is Apple engineers re-designed iTM to not upload a music file that was not purchased at iTunes. Period.
I currently have 260 music tracks 'waiting' and 'matched' in iTunes Store. iTunes Match goes through the full library each time I request to update the library. But nothing is ever matched and finally uploaded. I have removed 120 'ineligible' music files - originally purchased from iTunes and never modified.
To test the iTunes Match service, I repurchased 12 music files from iTunes, 12 from Beatport, and 12 from Traxsource. Not (1) ONE single track has been matched and uploaded over a 7-day period. Before the iTM disaster, all my purchased tracks uploaded in seconds. No file ID labels are modified, no alternative formatting is used; the test files were submitted to iTM exactly as received.
Like said, I relied on iTunes Match to manage my extensive music library but now that library is in complete disarray. Even my playlists have been changed by iTunes Match during the 'waiting to upload' period of time. This is 100% BullShitakke and a clear example of Apple's arrogance to The Customer.
Suggested work-arounds are described in this Community blog to modify our music libraries into an accepted state of iTunes Match. The engineers at iTunes are surely laughing their collective asses off reading these iTM requests for support.
So... does The Customer: A) wait until Apple's engineers decide to fix iTunes Match; or B) realize iTunes Match is a failed product and dump it. Either way, I want my money back.
