hey Judah! can I ask a favour? I've noticed there are quite a few new Messianic artists in Israel, only appeared in recent years.

Do you have the years of all the tracks or albums on your radio station? Can you sort/graph this to see what year is the 'golden age' for Yeshua music?

We could also use album year in Chavah's algorithm to help determine which songs to play for which users. Users that tgumb-up songs from the '80s would have Israel's Hope played more often, etc.
