Sorry, I can't help much; if at all. I can't even try out what you're doing.

With your `curl` command, I get:
< HTTP/1.1 403 Forbidden
< Content-Type: application/xml
< Transfer-Encoding: chunked
< Connection: keep-alive
< Date: Wed, 08 Nov 2023 16:46:08 GMT
< Server: AmazonS3
< X-Cache: Error from cloudfront
< Via: 1.1 4bc6659eecc0a4bfcaa0abdbfb655888.cloudfront.net (CloudFront)
< X-Amz-Cf-Pop: ORD58-P2
< X-Amz-Cf-Id: 3bDOrwF83c6bsn7_t_6lHgOnX904E0sl6XyHRRtOrKsjLHbns2gWMA==

And, with your `mpg123` command, I get:
[src/libmpg123/readers.c:1204] error: Cannot open file https://stream.io/thestream.mp3: No such file or directory
main: [src/mpg123.c:738] error: Cannot open https://stream.io/thestream.mp3: File access error. (code 22)

I see that Gstreamer has a GstDiscoverer command-line utility [1]. It provides a 'title' property, but I have no idea if that is 
what you need or if it is even accurate.
