Hi,
I'm Sumit, here to help with your query on the Microsoft Q&A forums.
Apologies for any inconvenience you are experiencing. I am happy to help you today.
I am afraid Windows Media Player does not reliably show the file system “Date created” for every MP3. WMP shows tag‑based dates (e.g., Year/Release date/Media created). If those tags aren’t embedded in the MP3, the column will be blank.
For a complete, consistent view, use File Explorer’s “Date created” or “Media created” columns - which is more reliable.
I hope you find this information useful. If you have any more questions, don't hesitate to reach out. Otherwise, please take a moment to accept the answer. Wishing you good luck!
