I suggested for Zeino to add the tag to the tracks in the pack. Especially if it's as big as it's aiming to be, it could be nice to distinguish the tracks from other tracks.
In case someone wants to upload their track to RVZ (not right now though, too many poor Lego tracks in a row, but that's jhu103's fault

), they shouldn't add the tag there.
You could also add the tag at the end, maybe between parentheses. Whatever looks nicer, I guess, as searching works for both, as long as you type an asterisk first.
