Samples are organized in their most common category, though the music in the Prelude/Bridal Party/Meditation category can, and often are used for processionals and recessionals.
Normally the couple picks a style of music for the prelude, then chooses a Pre-processional, Bridal March, and a Recessional - and sometimes a meditaion song if applicable. You can request specific songs during the prelude/postlude if you like.
