am not allowed to listen to the iTUnes song I bought

Ten years ago I purchased a song on iTunes with the Apple ID I had at the time.

A few years after, I changed email addresses and got a new Apple ID.

Today I couldn't open the old song. "Amazing Slow Downer" said the Apple ID that I bought it with, wasn't recognized.

The apple support page also says it doesn't know my old Apple ID.

I don't remember the old password and I can't retrieve a new one because I no longer have that email address. How can I play the song??
