A "REM@STER" version of a song is a M@STER version of a song rearranged. These new arrangements are at the same tempo as their original versions, but often sound completely different and include unofficial lyrics. All of these songs are either in THE IDOLM@STER MASTER LIVE series or THE IDOLM@STER MASTER SPECIAL series.
A shortened version of a REM@STER is a "REMIX", which is used to represent the new arrangement in the games. They are only audio changes in gameplay, and don't have any effect on image stats. There are two types of REM@STERs: REM@STER-A and REM@STER-B. These two rearrangements are both available in game, shortened into REMIX-A and REMIX-B versions. Most of these recordings were put onto THE IDOLM@STER MASTER BOX III, THE IDOLM@STER MASTER BOX IV, and THE IDOLM@STER MASTER BOX catalog 08,09,11 COMPLETE.
All of the following songs have received a REMIX-A and REMIX-B version. The REMIX-A versions are all exlusively unlockable in THE iDOLM@STER: Live for You!. The REMIX-B versions, however, are available as DLC for both THE iDOLM@STER: Live for You! and THE iDOLM@STER SP. In the SP game, they are under the name "-RMX-".
