No, J-Hope’s song Sweet Dreams is not part of a new solo album because it is a single, so it was released by itself and not with other new songs in an album package 🎶.
He put out Sweet Dreams with Miguel as a digital single on March 7, 2025, so you can listen to it on its own and you can also buy a special CD single if you want 💿.
J-Hope said he is working on more music and he will release more singles this year, so these songs will help show what his next solo album will sound like in the future, but right now, Sweet Dreams is not from a new album, it is just a single song 🌟.
If you like Sweet Dreams, you can look forward to more new songs from J-Hope soon, and maybe after these singles, he will make a new solo album for everyone to enjoy 🎤.
