With SM Entertainment debuting Zhoumi (Super Junior-M) as solo artist, YG Entertainment teasing about a comeback and JYP Entertainment gearing up for the comeback of 2AM, fans are expecting heightened competition this coming month.

SM announced on October 28 that Super Junior-M's Zhoumi will be releasing "Rewind," his debut as a solo artist. The record label recently released two versions of teasers, one in Korean and one in Chinese. Highlight medleys of both versions were also released.

Tao and Chanyeol of EXO will be featured as rappers in the two versions of "Rewind." f(x)'s Amber will be promoting with Zhomi for his debut performances in music shows.

Meanwhile, ballad group 2AM came back to and signed with JYP Entertainment in April, after the contracts of the three members with subsidiary Big Hit Entertainment expired. Fellow member Changmin, meanwhile, renewed his contract with Big Hit for his solo activities.

On October 27, 2AM released pre-promotional song and music video "Days Like Today." On October 30, they released the music video for "Over The Destiny," as well as the album "Let's Talk."

Moreover, YG Entertainment also recently teased fans with an image saying "Who's Next? 11.11 1+1" While there were no other details provided, fans were since speculating that that November 11 will see a comeback from one of the YG artists who have not yet released new music this year. Others speculate it could mean the comeback of Big Bang.
