A random thing I've gleaned after listening to Spotify for 2 days

I haven't given Spotify a lot of data to churn yet, but its algorithm has correctly noted that I like Warren Zevon. So when Spotify puts together its suggested music queues full of artists I've never heard before, I end up hearing a lot of Warren Zevon songs I've never heard, because Spotify has many Many MANY more Warren Zevon albums than I knew existed.Today I realized I always know the Warren Zevon songs within a chords or two, well before I heard his voice. There's a deeply identifiable signature to his music.Yes, I know, all songwriters and bands have a sound, but I've been known to ask, "Who's this?" about the same SONG many times before being able to consistently ID the composer/performer. That's a big indicator of  how unique Zevon's aural DNA are.But wait, there's more!To my ear at least, Warren Zevon's sound has something in common with Aaron Copeland's compositions. I can't begin to explain what that something is, but...especially in the slow ballads, as opposed to the hard bluesy stuff, the commonality is REALLY noticeable. I suspect this isn't a connection many (any) others would make, but it's there for me.  The sounds evoke similar feels. Something nostalgia-y, but not exactly nostalgic for anything I ever knew myself, more saudade-like, haunted acknowledgement of  something distant in time and space.ANYway.I just wanted to make that observation before I forgot it. So I shared it.That's all for now.
