You get new speakers or you start your music library from scratch. Which is the first song/album you play?
Recently I switched from Apple Music to Spotify free/Navidrome. I am moving my library to Navidrome slowly. I have done a similar thing in the past as well.
I noticed that both times, as well as trying out new speakers, the first song I listened to was In the End by Linkin Park, followed by their latest album.
What is yours?
Edit: Holy Shit! I was not expecting so many replies. It is not possible for me to reply to everyone right away. I will listen to each of your first songs and reply to everyone.
I test every new headphone and speaker system with Watermelon Man by Herbie Hancock. So many layers to the music that gets washed out on poor setups so it's great to check dynamics!
Genesis by justice for the bass and delight by jamie berry to test how they fare with cymbals and trumpets (i found that if a speaker has problems with the band pass filters/ channel separation it sounds awful).
Plus they sound awesome for their respective genres.
Just such a gorgeous piece that spans the whole spectral range and has a wide dynamic range. Really intricate details from all the instruments involved too.
Its a beautiful way to experience a new set of speakers and also to dial in the balance on the EQ.
i set up lidarr + streamrip with a script that gets albums missing from lidarr, and then tells streamrip to download them from tidal
so if i were to delete myusic collection, it would download 2WEI - Emergence first, as that is currently the most recent album of the alphabeitally first artist i track
but answering what you actually mean, it'd be Machine Head - Of Kingdom and Crown
