After a brief hiatus, Show! Music Core began airing on October 29, 2005 with charts similar to its predecessors. However, the charts were removed on January 7, 2006 and continues to air without any charts or awards. Even without the weekly chart award, the show was known for its special production and stages.
From 2007 to 2008, a Mobile Ranking segment was used to rank the popularity of songs downloaded to mobile phones and from online music sites.
In March 11, 2013, MBC announced they will return their chart system after 7 years without the segment. Ranking system was reinstalled on April 20, 2013 with first place trophy given to the top song amongst the nominees on each week.
Music Core brought back the show's chart on April 20, 2013. First place winners are determined using the ranking system below. List also shows the current and former scoring computation used. As of June 8, 2013, 4 nominees had decreased to 3 nominees.
Epik High received the first ever Music Core award on October 19, 2005.

In a first on the June 8th episode, none of the number 1 nominees (Beast, Lee Hyori, CL) were present at the live broadcast/recording.
On the March 22nd episode, none of the number 1 nominees (Girls' Generation, Soyou & JunggiGo, 2NE1) were present at the live encore.
Chart Winner Mix-up
On the April 20th episode, MBC has introduced a brand new ranking system for ‘Music Core’, and as such has nominated INFINITE, K.Will, Davichi, and Lee Hi for #1 on the charts. K.Will was mistakenly announced as the winner. He looked confused as if he couldn’t believe it, and as he was about to say his thanks, the ‘Show! Music Core’ staff quickly informed everyone on stage that there had been a mistake and that INFINITE were the actual winners. K.Will was quick to laugh it off and say, “It’s okay, I’m okay.” He even shouted, “I love INFINITE!” However, the INFINITE members themselves looked unsure and confused about accepting the trophy.
Afterwards, the staff of the show was highly criticized by viewers. The staff made a statement on their official board and said,
"This is the ‘Show! Music Core’ staff. There was a mistake in announcing the 1st place winner on the April 20th broadcast. This was a mistake because the text votes were mixed up for the two 1st place nominees. The two team’s scores are 100% fair results. The text votes accumulation company has promised to work harder to keep this from happening again. Please excuse us for not running a smooth live broadcast. Thank you."
