"Amarok 2.1 now suports replaygain (both track and
album mode).
"This is one of my favorites aditions. I used to abuse the
replaygain script in the 1.x series, and now this great feature is
suported natively by amarok 2.1, using a mix of taglib and other
magics.
"Till now amarok can READ replaygain tags for pretty much every
audio format you can throw at him. The devs talked a little of ways
of adding write support (reading non tagged files and calculating
the replaygain) like a plasmoid and such, but for now, amarokers
can use the excelent (kde 3) soundKonverter for writing replaygain
tags for their collections.
