The physical retail arms have been kept separate, for different customer bases and brand identity, but the e-retailing, wholesale and distributor business is unified as Rose Tachung Records.

The two chains originally teamed up to create Taiwan's popular music ranking, the G-Music Chart (Chinese: 風雲榜 fēngyúnbǎng).

[4] Tachung's network includes Taiwan's only remaining specialist classical CD store, opposite the Taipei YMCA on Hsu Chang St.[5] G-Music Chart remains the most popular record chart in Taiwan.

[6][7][8][9] The G-Music Chart was first officially published on July 7, 2005, and compiled the top physically sold CD releases in Taiwan (including both albums and physically released singles).

Only the top 20 positions are published, and instead of sales, a percentage ranking is listed next to each release.
