Something similar that has bothered me in the past...

I have paid additional $$ for extra paks of RealTracks then in the following year found those same RealTracks included in the upgrade and referred to as new RealTracks. I only discovered this because I was thrilled with some baritone guitar tracks one year and hoping for more the next year. Then I saw "new" baritone tracks in the following year's upgrade but they were the same ones I bought previously.
