iTunes Match. Should it be like this?

Having just purchased the new 21.5" imac. And already owning an iPhone 4S and an ipad 3rd gen. I decided to purchase iTunes Match. Especially with the new update allowing you to download individual tracks to your devices!

Now I know that £21.99 isn't a lot of money for 1yrs subscription. Bit it is if it makes a mess of a well organised library!!

I really should have read up a bit more about it on here before I went ahead and purchased.
I have a library consisting of approx 4500 songs at present. With the majority being 128kbps mp3's. so one of the attractions was that as apple state, you could re download a better copy (256 AAC) if it is matched in the store!
But was amazed to find that approx 500 songs were uploaded instead of matched even though they were in the store!
Nearly every album bar a few have at least one uploaded track. For example. I have every single AC/DC album. And the first track on'back in black' will not match even though it is in the store. I have tried everything from converting said track to AAC. to deleting it and downloading again!!

Surely this has to be a problem at the apple end. I'm just a bit worried that I have made a total mess of my library. As I started to erase quite a few albums and re download from the cloud fr better quality. But now the sound quality isn't consistent across an album because some of the tracks are of a lower quality!
I never did a backup either of my originals. Will I still be able to recover them in 'time machine' !!?!

Another infuriating issue. Is the 'genius' playlists that are appearing on my ipad with no way to delete!
It isn't as bad on the iPhone as the playlists are sort of hidden. So finding and playing music isn't as problematic!
Why apple removed the ability to turn off genius in itunes is beyond me!!
I really thought that coming from a windows pc to a mac would simplify things. But thus far I have encountered numerous problem. This being the icing on the cake. Windows media player was just so simple to use compared to itunes!

If anyone has any input or could enlighten me it would be most appreciated!

Always, always, always keep a local copy of your files. Especially when downloading new versions to update your library.

As for some not matching, that's totally normal and is an issue on Apple's end.

Hang in there, iTunes gets easier as you use it. It's taken me many years to master it. I'm also not sure why we can't turn off Genius since we can for apps. Seems odd if you ask me.

Thanks for your reply HazyCloud.

I now realise that I should have backed up my music files. But could you please just confirm one thing!!?!
The albums/songs I have deleted and re downloaded from the cloud. Will they be keepers now? If I right click to show in finder. They are showing as saved!
If this is the case. I think my library is ok apart from certain albums I have mentioned having the odd song at the old bit rate as it was uploaded!
Also. If I don't re subscribe. The way I have read it is that you still keep the songs you download from iCloud!
