What do you mean "Play from tracks that are from the 70's, 80's, 90's"? I haven't got any, what about the 30's, 40's, 50's & 60's?
LOL, yes, that feature wasn't very thoughtfully implemented first time round. It's FITNR, and all my William Byrd choral music comes up as "Sounds of the 1590s" as intended.
