After some time dedicated to troubleshooting this, I'm coming up empty-handed. Hopefully someone can figure it out!
Before I elaborate on the issue, I've verified multiple times that I'm selecting the exact same "Mr. Brightside" to play on my iPhone and on my laptop.
When I play Mr. Brightside on Spotify on my laptop, it plays a version with much higher gain that sounds a lot more 'raw' (if that makes sense) - more akin to the original demo version/first recording of Mr. Brightside. This is what it sounds like:
However, when I play it on my iPhone Spotify app, the version that is being played sounds similar to the professional studio recording on the album Hot Fuss, like this:
I've tested this on multiple audio outputs (various speakers I have at home, my car speakers, headphones, etc.) and I can hear the difference all across the board.
I've saved and removed the song from my "Songs" list under "Your Music" multiple times to verify that I am in fact selecting the same song, yet, it's different on my iPhone and laptop.
Any ideas? If I haven't been clear, just let me know! It's a little complicated to explain in written form, and I'd be happy to re-phrase or explain it in another way.
