How many songs can the 16Gb iPod Nano hold?

At about 250 songs per gigabyte (GB), a 4GB Nano would hold 1,000 songs, an 8GB Nano would hold 2,000 songs, and a 16GB Nano would hold 4,000 songs. This is not exact, because the number of songs stored depends on the song length, the compression used, and even the music itself. The above standard estimate of song capacity is based on 4 minutes per song and 128kbps AAC encoding; actual capacity varies by content. If some of the Nano's storage space is used to store other files, such as photo or video, then of course the space remaining for songs is reduced.
