Any song recommendations for testing purposes?

Hi y'all,

So me and my pal came up with an idea about testing our own " streaming system " and see which is better, but yeah ofc, there can only be one variable, otherwise the test wouldn't be fair, no?
we decided to only change the streamer/player in each test, well luckily, my friend who happens to be an ultimate PC Hi-Fi fanatic, so the test itself which became rather easy haha, equipment-wise for sure.

Last Sunday, we were just chilling in my living room and chitchatting, he said he wanted to listen to some new modern pop song, so I played Shiver by Ed Sheeran, and he said the dynamics don't seem quite enough, I was like what the heck do you mean, and he said his system could present more details in the music than mine, anyways, so I brought my streamer over to his place, and would like to have a competition hahaha.

As I mentioned, he's a PC Hi-Fi dude, so he's done a lot modifications and all that upgrade stuff to his PC, so he used USB port to connect to his DAC and the rest to play the same song, Shiver by Ed, well truth to be told, I also thought the dynamics weren't quite sufficient as well lol, ofc he said my perception was biased bc he judged my system first, thus, we both agreed to play some more complicated tracks, like classic genre or something, however, both of us aren't that much of a elegant music admirer I'd say, which I sincerely hope you guys can share some nice songs with me!!!

BTW, we both played TIDAL via Roon, the only difference is just he used PC, I used Munich M1T, no network switch or linear power supply attached.

Best,
