My go-to is just “my radio” on Apple Music because it plays a large variety of hits and deep cuts of music in my library / that I like while sprinkling in new and old stuff that I don’t have or haven’t heard. I’ve discovered so many great songs and artists over the years by just asking Siri to “play some music” it’s effectively endless good music that can be switched up any time if I want a different vibe by simply re-asking the same question or saying “play something different”.

Otherwise a solid go-to for me is the lofi beats to study to radio and many of its sub-specialties like lofi synthwave or lofi jazz or even lofi christmas.
