Our latest international app (Spanish) and album cover reveal is for Reik. Fans can connect and share the message on Twitter or Facebook to collectively reveal the new #YaMeEntere album cover. The more fans share, the more squares unlock, slowly revealing the album cover. When the app reaches 100%, the album cover is completely revealed. You can check it out here: http://www.tweematic.com/reik/
