I am curious about what kind of music this community enjoys.
Music recommendation algorithms don't work well for me, not even the highly advanced almost-AGI-level algorithms of Spotify. They tend to be conservative and keep me in a bubble. I found my best new music by asking people for their favourite songs. This approach seems to offer a highly efficient search across the music graph.
If you can explain why you think that song is perfect, that would be a bonus!
I've been playing music for many years and have thought of many songs as "perfect" by various musical criteria, melody, beat and so on. But deep down I think musical criteria aren't the answer. It all comes down to which mood the song puts you in, so the perfect song = the one that hits the right mood at your current stage in life. So it's gonna be unavoidably different between people, and for the same person across time. For me as a teenager it was "Losing My Religion", somehow. Now at almost 40, this recording of Aguas de Março makes me smile.
The song Inama Nushif composed by Bryan Tyler with vocals by Azam Ali always tops my list. It is a beautiful song. Inama Nushif cleverly uses the fictional Fremen language. I can't say much more without spoiling Frank Herbert's Dune novels and possibly future movies. But when you compare the lyrical translation to the tragic fate of the described character, the irony will break your heart.
I definitely don't think any human-made song is perfect. (Do you claim a superintelligent AI would be incapable of improving it? If yes, I question your models; if not, in what sense is it perfect?) But if you're asking me for music that I think is extremely good, leaving it up to me to decide what that means, the first thing that comes to mind is Program Music III. I would recommend the best song but there only is one song, so I'll recommend the first 12 minutes.
If you like Steely Dan you may just get Weather Reports output from the early eighties - Procession, Domino Theory and Sportin' Life. Omar Hakim on drums and Victor Bailey on bass. Confians isn't typical of their output but it is so heartfelt. I am told it is sung in a Brazilian creole, but I have not idea what it is about. But then again, I do.
Shpongle consistently pushed the envelope of electronic music, always creative, always original. For example...
