So I think many people love the song "Waves" and it's 2000s boy band vibes. We just had the anniversary of its release this week for the Another Life album. I loved the colors and the sound the song is so good and I would not complain if they kept it for their fifth album.
" Can't Get Enough" apparently some thought had a similar vibe, and them performing "Forget You Now" with lasers on tour gave that also for me, and James was right it did look cool having lasers. The guys have only released two songs since that album: "Only One" and "I Want You Here All The Time".
They been slow with music, but I think a 2000s vibe would suit them well. That was the peak of boy bands and chereography and the outfits were so good. Everything was good and I do not wanna get redundant with my point so I think they should adopt a 2000s sound for their new music, along with outfits and everything. I know they may be kimda burnt out from touring, but this would probably work.
Nothing wrong with their current sound of course but yeah. I think it was working for them and maybe if they wanna find their sound outside their Nickelodeon-era music this would be the way.
