SEGA games, both current and old, often have the chance to benefit from quality soundtracks (and even cult in some cases). The Japanese publisher is aware of this and intends to redouble their efforts to commercially exploit all of this music.

SEGA just announced in Japan the launch of SEGA Music, its new subsidiary whose mission will be to manage the marketing of the soundtracks of its games. The first CD to be released under this new label will be Sakura Wars Complete Collection
SEGA specifies however that it will not directly publish the original tapes. He will continue to work with various traditional labels. However, he will use this logo to indicate to consumers his involvement in this project.
At the time these lines were written, the Japanese publisher did not specify whether it intends to exploit this label outside of Japan, in Europe and in North America for example.
And for the record, the waveform seen on the SEGA Music logo corresponds to the little "SE-GA" that it was possible to hear at the beginning of old SEGA games (on Mega Drive for example).
