To celebrate MEIKO's 15th anniversary, we would like to see more MEIKO's songs! So we decided to run a song upload campaign! Because we want everyone to feel pleasure while attending this campaign, and this is a campaign for 15th anniversary by fans, so this campaign won't have any ranking, this is a "Song exhibition"!BLOG: https://meikogr.hatenablog.com/Twitter: https://twitter.com/for_MEIKOpiapro: https://piapro.jp/collabo/?view=collabo&id=28835
