One word may not meet your requirements, but I know the characteristics of each forum:

Comprehensive ones: Xuanyin Music Forum (unclear), Ba Ling Music Forum (relatively rich in resources, high sound quality,)

Pepsi Music Forum (mainly 320k code rate, better classification, many ftp resources, many singles)

Zha Sui Backyard ( The songs are relatively comprehensive, but rare songs are hard to find)

91ting Music Community (more whole tracks)

Deep Music Forum (less resources, but divided into tracks)

The Voice of Chutian (mostly nostalgic old songs, all ripped from good discs)

Google Music (192k bit rate)

I just love ape (direct download from Thunder, full speed, songs Few, they are all famous songs)

There is another website that I won’t mention. You must use express train to get off. The single-thread speed is super slow

There are also many forums, search on Baidu: Music Forum
