According to Nas’, the first single from his forthcoming album is a diss track to Jay-Z, “Stillmatic”, so it appears the track is not a freestyle after all. The site also confirms that the new album will be titled “Stillmatic” and NOT “Nastalgic”, which was the given title by hip hop magazines earlier this year.
Nas himself said a few weeks back that the new album will drop on November 13th, but the site says that the album will drop Fall 2001, so the album may get pushed back at any time. HipHopDX will keep you posted on any further details.
