Software question

Howdy howdy,


I play this sport called "disc golf" with some friends and my digital camera has a little movie option that I use frequently to tape our games.

Anyways, I've been meaning to find out a way to add music to the clips and also piece the clips together somehow.

Any reccomendation as to some useful and easy software I could use to aquire my desired need.

Appreciate it,
I'm lost as always with computer stuff...
