Other villages in the municipality included Brennåsen, Finsland, Kilen, Nodelandsheia, and Volleberg.

The Sørlandsbanen railway line ran through the municipality, stopping at Nodeland Station.

On 1 January 1978, a small area of Vennesla municipality (population: 10) was transferred to Songdalen.

The official blazon is "Vert, three oak leaves in pall and three acorns in pall inverted stems conjoined Or" (Norwegian: I grønt tre gull eikeblad i trepass med eikenøtter mellom).

This means the arms have a green field (background) and the charge is three conjoined oak leaves with three acorns.

The charge has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used.

Songdalen's administrative centre, Nodeland, is a short 10-minute drive from the center of the city of Kristiansand.

The river Songdalselva flows through the valley that made up the southern part of the municipality.

The river passes through a 1 kilometre (0.62 mi) long, 100 metres (330 ft) deep scenic narrow gorge called (Juve) at Underåsen.

The municipal council (Kommunestyre) of Songdalen was made up of 25 representatives that were elected to four year terms.

An 8-kilometre (5.0 mi) long section of the old Vestlandske Hovedvei (Westland Highway) passes through the municipality from Farvannet to Kvislevann.
