Title explains it all. It can also be a remix album. But there are some guidelines for you gurls:
- There can't be any new songs, by name. You can put "New Song" if you want too, though.

- Only SINGLES. It wouldn't make any sense to include an album track that is virtually unknown outside of the artist's stanbase.

- If you want to create a remix album, there can only be OFFICIAL remixes. You can't include some unofficial YouTube mix or something similar.

- You have to have at LEAST a title and tracklisting. The titles can be as simple as Greatest Hits. You can add a cover, disc design, and other things if you really want to.

- It has to be at LEAST one disc, and at MOST three discs.

- The songs don't have to be exclusive to one era.

Go crazy, gurls.
