gracenote for pre master promo discs ?

[L_B]

Hi, newbie here so sorry if this is not the right place for this post ..
Am just embarking on my first DIY release;

I'm sending out some promo cdr's for review (pre mastered - just ran mix through L2 cd mastering setting to get it nice & loud! mix is great already so ok for promo purposes.), and wanted to add the disc to gracenote so that any potential reviewers can see tracks on itunes/ipod >
Is this a bad idea pre-mastering ?
I am getting the album & a 7" mastered at a pro mastering place in two weeks - there's just no time to get that done before promo's have to go out.
Was just concerned that something might conflict if mastered copy is slightly different to the promo copy on gracenote system.. Is this likely to be a problem ? or indeed a stupid question ?! No problem having two discs of same album show up on gracenote I guess (?!)

any advice gratefully received
many thanks

As new/different version, the 2nd release should be labeled in a different way. So just call Demo or Prerelease the one you register first.

but if gracenote works on track length/numbers, then wont both pre master & post master discs be seen as same ?
I wonder if I should just enter promo disc details as final copy in this case ?

Add some extra time to the end of the demo.
