Do i need a SPDT or a DPDT switch for my car lighting?

Id like to have three independent circuits running for different parts of lighting in my car.

One switch position must be constant on connected to a 12v source

A 2nd position must be OFF

A 3rd position will connect to a sound module so that the lights can flash to a music beat

*the 3 individual circuits will be run from a single sound module, but each on their own switch.
This is so, for example, one set of lights can be flashing while the other two are constant on, etc.

Can anyone tell me what type of switch ill need for this? Thanks.
