I recently put together a collection of o2jam charts that I've converted to work in Osu!Mania. Every map is 7k only, but there are a bunch of easy charts there that are easier than playing standard ranked maps. The idea was to create a collection that people new to playing mania could learn with, as well as songs going all the way up to pro level.
The name of the file tells you how hard it is: [e1 n1 h1] IL-RA - [Easy]Just 1 more (NoteFactory).osz
The part that says [e1 n1 h1] tells you that easy normal, and hard difficulties are all o2jam difficulty level 1 (the easiest difficulty level in the game).
Everything in the main folder is an official o2jam map (from the PC game, not o2jam analog. Nobody owns the rights to these maps now).
Everything in the other folders is custom charts. Many custom charts are harder but some stuff have easy difficulties.
Here's the collection: http://www.mediafire.com/?qsk9mqzkx45eg

Maybe sometime when I've got it a bit more complete I'll make some packs. I'm still planning on adding to the collection for now, so I'm not going to create packs quite yet.
