I laughed when you said they don't seem that playful 😅😅 Yes, they seem mature because they are very professional and they've been through a lot. They do have light-hearted songs, of which someone else has already given you a few examples. They also have a lot of fun stages. HOWEVER.....what you don't know yet is that they are the most hilarious, chaotic, unfiltered, goofy, naturally funny group you'll come across.
Don't Call Me was a Korean album, and Atlantis is the repackaged album, of which the single Atlantis was released. Maybe you were thinking of Superstar, which was their follow up Japanese mini album. :)
Look forward to your SHINee’s journey ❤ many good song/ms from them: replay, view, Why so serious, sherlock, don’t call me, everybody, juice, tel me what to do, selene 6.23, dear name (cover), etc
I actually didn't like this song on first listen but it's really grown on me. It's also shy-knee instead of shine. As a second gen group they have a different vibe. Onew is tha beast!
