GOT7's Youngjae has opened up a SoundCloud account!
He linked to the account on his Instagram. When fans follow the link, they're gifted with a Youngjae-only version of "Hey", the song he wrote for the album. It's the guide version, which means this is the version the vocalists listened to as a guide to record the GOT7 version.
You can check out the guide version below and his SoundCloud here!
