In Blind Guardian song Curse my Name, there is a high pitched beep that ruin the song. (This is a well known issue, you can read about it here). I fixed the song using audio editor but now, I can't upload it to Google music.What I did :Right click on old song, delete this song.Using Google Chrome, I upload the fixed song by drag and dropping it in the Google music window.Once the upload finished, I go to Latest upload automatic playlist, and there the song is the deleted one that has been restored.I deleted it againI edited the mp3 ID3 tags (hopping that Google music will identify the song as a new one)Re-uploaded, same result. The old deleted song is restored.How can I upload my edited version of the song?Edit: I finally managed to upload it with the Google music manager client and Firefox, but I'm still curious to know how does Google music identify the mp3 file.
How does Google Play Music identify mp3 file?
google music;audio;mp3
