Time-Based Smart Playlists

[mrbvcn]

I'd love to see a feature that allows a single playlist to change its playback based on the time of day.

The idea is simple: you create one playlist with all the songs you want, then assign different songs to different time ranges. When the feature is enabled, Spotify automatically plays only the songs that belong to the current time period.

For example:

* During the day, the playlist plays energetic and upbeat songs.
* After 9:00 PM, the same playlist automatically switches to calmer, more relaxing tracks.

This would let users keep a single playlist instead of creating multiple playlists for different moments of the day. It would be perfect for people whose music preferences change depending on whether they're working, relaxing, studying, or getting ready to sleep.

An optional enhancement could be allowing multiple time slots (morning, afternoon, evening, night) and even different schedules for weekdays and weekends.

I think this feature would make playlists much more dynamic and personalized while keeping the listening experience simple and seamless.
