Next-Gen version of NSP has Lorde, so that officially makes it the best station in the series, obviously.
That's it? Only because of one artist? It's like me saying "Space 103.2 is the best radio station ever because they play Bootsy Collins and Zapp" (that's why I listen to that radio station).
@OP I can agree with you, East Los FM is one of the worst radio station in the series, it's actually embarrassed for me to say that because I'm part Mexican, I don't know any of those artists except for the Los Ángeles Negros.
EDIT: and the DJ and that song El Sonidito? GOD!! Unbearable!
But there is two more radio station I hate more.
Radio Los Santos (On 5, not SA). There was only two good songs.
Swimming Pools (Drank) By Kendrick Lamar (PS4, Xbox One, and PC only).
Hood Gone Love It by Jay Rock feat. Kendrick Lamar.
My all time least is (believe it or not)...
