There are many songs that came recently, you just have to keep being updated thats all.

You can start with Kagerou Project songs if you want, they are very popular and there are many songs which uploaded only in 2013.

You can subscribe to some Vocaloid songs uploaders to keep on track with all of the new songs and stuff, and even old songs is good to cover. Iroha Uta is my favorite Vocaloid song and its from 2009, nobody really cares if the song is old or not.

Sorry if my English wasnt really clear or something, I dont keep my grammar well if I type fast or something ^^"

ok, Thanks! 

I also have a few other questions :

I wanna become a NND Utaite, now, the problem is, idk how to exactly 'format' the title and descriptions and such....

Also, i'm unsure of what 'mixing' exactly means, what happens in that proccess precisely that amplifies the quality of the cover.

In the title you can write the song name with 歌ってみた [which means tried to sing] with your utaite name in many formats, you can just decide whatever you like.

I dont really know much about mixing, I guess somewhere in the "Beginning Singers board" you can find you answer

About descriptions I think you cant just write like:

■vocal：your utaite name (mylist/x)　(cox)　twitter [if you have]

■mix：(the same)

■encode：(the same)

and link for the original song

Thanks, just what are the (mylist/x)　(cox) and encode things (excuse my lack of knowledge, i'm unfamilliar with these kind of things)

Also, i can't seem to find the uttatemita section in the NND site...

You can find information about mylist where I linked<

community is where you can upload covers and only your community can listen to it 

About encode I dont really know myself, so I'm sorry ><"

Adding on some stuffs here:

Oh, check out the VOCALOID ranking additionally, to get the current most popular VOCALOID songs.

It's got hourly, daily, weekly, and monthly ranking. (Monthly ranking is probably most significant)

By the way, here are some old classics, that are alyways nice. The most popular songs here (all VOCALOID songs ordered after view count)

Oh about the video title, some people have some kind of 'trademark' thing, like Senra writng 歌ってみたラ, or Bronze Arm Drive with それはもう大変僭越ながら[songname]を何でもありません and Lon with only 歌った ;DD Be creative!/shot but yea, [Songname]を歌ってみた plus singername is most basic. (Supposing you want to be active on Nico Nico Douga, not YouTube)

In the description it's important to credit people, some utaite even go as far as crediting everyone from the original video ;DD but that's.... not really necessary. But also people usually write one/a few line (s)/comment in the description. I'd suggest you looking at some descriptions of other utaite and see what they write? XD Again, be creative!/shotx2

I think communities are like premium member only though...

Here's the Utattemita ranking and the section you can find here under エンタメ・音楽 then 歌ってみた

Encoding has something to do with the video, where you format the video properly, I think.

Thanks alot just, i can't seem to find that damn upload button....

^Is me, what i meant was, that i couldn't find how to upload to that specific section.
