Big Ears Required

As we know, there are known knowns; there are things we know we know. 
We also know there are known unknowns; that is to say we know there are some things we do not know. 
But there are also unknown unknowns – the ones we don't know we don't know. 
And if one looks throughout the history of our playlists, it is the latter category that tend to be the difficult ones

Please help us identify tacks 25, 26 & 38 from PSA002, then our records for the first 36 missions will be complete.
