N/A means it's not available as was mentioned and you won't find it in the sets. Each level of BB that you buy has more tracks than the previous level. AND.... there are additional track sets you can buy as add on.

I believe if you do not have the track in your purchased version, BB will substitute a suitable equivalent track so you're not missing the bass or piano for example. The way to get that track is to upgrade to the next version that does have that track in it.

You can make excuses or you can make progress but not both.
