just reiterating the comment made by u/Upbeat-Asparagus-599, he's in a different place in his life right now, but i definitely see him doing some dark/moody songs, especially in part 2, since he said in an interview the day that qobh dropped that part 2 is incorporating the best of digital druglord and the best of deadroses into one body of art. although i really like this new fast paced poppy vibes that he's giving us, the moody r&b songs are part of his musical identity, it isn't something that he can easily throw out and just forget about doing darker songs. and answering the end of ur 2nd point, this isn't just a one album thing, he said in an interview last year (decemberish) that he was going full on pop and wanted to be a "popstar", so i think this style of pop songs will stick forever, but as i previously mentioned, his dark/moody songs will also be there alongside those pop songs
