Why has iTunes Match uploaded these songs?

[MasterHowl]

Hello,

Loving everything about iTunes Match so far, brilliant service.

Just a bit confused as to why it's uploaded some songs, and not others, even if they were from the same album? See the screenshot to see what I mean:

I mean, I'm not fuming about it, I'd just like all my tracks to be 256 kbps if they're also on the iTunes Store ^.^ It's done this with loads of album!

Thanks

could be incorrect or incomplete ID3 Tag info.

I have a few problems with that too. I have just under 10k songs in itunes, It matched just over 6k last night and tried to upload the rest. Albums such as Adele 19 & 21 etc. I stopped it and will be going through with Tag & rename or something to make sure the id info is correct.

Are ID3 Tags the album name, years, artists etc?

And once they've uploaded, can I "un-upload" them and the match them up?

Thanks!

right click on the track in itunes and go to get info, its the stuff in there that will be slightly out more than likely.

But yeah your correct with most of that.
