Hello, first i wanted to say i love this app, I’ve been looking for something to play my plex for a long time. the plex app has some random play buttons but the one i find i use the most is called time travel button. that would be great to have.
Since I have no idea what that button would do from the name you’ll need to be way more explicit about the actual need 
i think and i might be wrong but a random button based on the year of the album. this would mean i would have to fix my library though
I still have no idea of what you are trying to explain
Do not try to describe what you imagine the button does, but what your need is the more precisely possible.
my apologies. I would like to see a button that would play a random album based on release year. for example it would play one song from an album released in 1986 then a different album based on an album from 1995, and so forth. i hope this makes sense also, it would be nice to have a feature where when you shuffle, the current song will crossfade into the next. not sure if i’m explaining it correctly, here is what i found.
Crossfade
I’m sorry but it’s even more unclear now 
What is the relation between 1986 and 1995?
For crossfade this is currently not supported by the player I use.
