Now that the file gallery is working, I've started to tag some files. This are some of the proposed tags and their meanings:
anachostic: Anachostic plays on the track
macsnide: MacSnide plays on the track
solo: A one-track performance
studio: A single or multitrack performance under controlled settings (overdubs, retakes). A studio recording can be played live in a limited format.
sequence: A single or multitrack performance that cannot be played live.
live: A single track performance played in a live setting.
kid friendly: A song that would appeal to children.
offensive: A song that has adult themes, swearing.
That's all I can think up now. There may be more later.
