Tonight we're having a 50's party! I'll be Elvis! However, it seems impossible to find music suited for this. Ie, music from the fifties. I have searched for "1950" and "50" and so on. Elvis is easy of course. I've found a "100 top of the 50's". But I want more. I'm convinced that there could be like one thousand more playlists containing music from the 50's, but I can't find it. What am I doing wrong?
