I just thought of something else - we should also add the option
to choose whether to encode only the beggining or the end of
the song without the psychoacoustic - because, for example,
if you have an album with tracks 3 & 4 that are gapless, then
it is only necessary to encode the end of track 3 and the
beggining of track 4 without psychoacoustic so that they could
match. Even if the whole album is filled with gapless songs
(like live albums), the beggining of the first track & the end
of the last track should be excluded...
