...whoa, I did not expect such a response haha, thanks for all the suggestions, guys! ^^ I've taken a look through the suggestions (most of zeila's list hehe, thank you <3) and bookmarked some of them to learn myself hehe

That said, not every arrangement everyone suggested can be considered pick-up-and-play easy, and if I have time I'll explain why. I think a good gauge is as Zunawe said:
My mark for this is that I've actually been able to learn these:
Yes, we're all at different standards of performance, but a sheet is easy more because it is pianistic than it is technically simple. Basically, the more suited your writing is for two human hands on a piano, the more simple it is to learn and execute. For example, scales are quite nice to play at a comfortable tempo, arpeggios less so (left hand would be naturally better-trained in this), right hand parts with too much overlapping between the middle and lead voice are surprisingly hard to learn even if it looks easy. If you can play your sheet without frustration without too much work, chances are it's quite okay - the piano fundamental skills are kinda similar amidst all players ^^

And now, about organising this xD
In the OP, you should keep a list of the stuff you've added and a list of stuff that has been suggested but doesn't have a video yet. People might contribute with their own videos. Especially if these are easier pieces.
...the problem with this is that it involves an OP that has to be updated. And the current one is quite cluttered as it is already. And, um, and...I'm not making excuses at all.
(haha i'll get off my ass this weekend to organise the op ^^)
Meanwhile, I'll be scanning through the list to find about ten minutes of music to shotgun this weekend! ^^ I think the way I'll do these on my end is in compilations - gives it the whole browsing/shopping kind of feel i believe~
