Can you try it with Tom's Diner by Suzanne Vega? It's sung without any instruments, and an early version of MP3 reportedly was a disaster on that song.
At some point she sings "loose" instead of "nice" in the compressed version, and a bit later it also sounds like "lulk" instead of "milk". So it's a bit lossy even with respect to the lyrics!
Curious, it definitely works, but the domain is "weird" enough that certain firewalls or proxies may have trouble, perhaps. I've put it at https://gofile.io/?c=F5gle3 as an alternative.
It holds up ridiculously well considering the entire song compresses down to 25392 bytes.
