Welcome back! If you need more time to think about what to do take as along as you want. As for the recommendation of videos you could do, maybe you could do some Vlogs, Challenge videoes, or videos where you talk about unsolved mysteries? That's all I can think of right now.
Hope you see this. As for content, you are talented enough to pursue any avenue. Seriously, you have the skill/talent/charisma that top RU-vidrs need to succeed. You need to choose a definite direction with the channel though. Is it music? Is it marketing? Is it internet news? You can do all of it but you'd need to upload 3-5 times a week. Use pewdiepie as an example. Meme reviews, game plays, reaction vids, book reviews, cooking vids, reddit etc.. multiple angles but almost daily uploads to cover all those bases. OR you can choose to focus on 1 particular topic and upload once a week like most other RU-vidrs. You really do have the talent to choose your destiny on this platform but that's just it, you have to choose what direction you want to take. I saw your comment on everyday astronaut's last video at 7.5k likes. People know who you are - they just don't know what to expect from you. The world is yours.
Oh also as for channel content, I personally love the music industry insights. But some other content sprinkled in would also be appreciated. You have a catchy personality so whatever you decide on I'm sure will be great!
It would be super cool to see you do some solo work on this channel. Just like covers and such. I would love to hear you experiment with lots of genres and techniques
