Fans of the band have been waiting anxiously for new material since the release of Feelings back in September (15). But now Adam, 37, who has been kept busy with his commitments on US television talent show The Voice, has promised something fresh is on the way.
"Not an album right now, but maybe a song. Gotta keep the kids interested. We have something going on right now," he told Entertainment Tonight. "Soon, it's coming... It's on the way. It's in the incubator."
One musician hitting the headlines this week has been Beyonce, who released her album Lemonade on Saturday (23Apr16). The album has already received critical acclaim, with many praising the singer's decision to directly tackle such issues such as police brutality, race and feminism in her lyrics.
However, Adam suggested Beyonce's approach to songwriting was something he had grown out of.
"I am a fan of heavily shrouded metaphor, so I don't like to do that," he said of Beyonce's new material. "I used to like to do that a long time ago, but I like to keep it to myself and let people interpret it for what you want. I think it's more fun that way because then I can kinda exist behind it and it's like, a little more mysterious."
Despite his comments, Adam insisted he is a massive fan of Beyonce and what she is doing through her music.
"I really respect actually seeing people living through their art, (it's) a really inspiring thing," he said. "It's real art because you're like, 'OK, this is exactly what this person's going through, this is exactly what this person is feeling.'
"I'm more afraid to do that now, which I don't think is a bad thing, because you can still be artistic that way. But it's definitely enviable and really cool."
