Some examples of emblematic music that are often used as specific references:

Chariots of Fire https://www.youtube.com/watch?v=TYJzcUvS_NU

Wagner's March of the Valkyries https://www.youtube.com/watch?v=XRU1AJsXN1g

Gonna Fly Now https://www.youtube.com/watch?v=cyvQKTg4T5o

You can't really replace those.

I'll be happy to never hear either the first or third examples ever again. It shouldn't be a big deal to find public domain performances of the out-of-copyright Wagner piece.

No, there really isn't, or advertisers wouldn't be buying public performance rights anymore.

Advertisers either want a catchy song people already know, or don't want to attribute the artist. Neither are a problem for streamers.
