Help, I cannot get my head around the storage options.

I have an external memory card that I would like all my songs stored on without copies made on my internal memory.  I thought I had achieved that until I took out my memory card to rename some albums that were given numbers when I batch imported them (1 followed by 10, 19 followed by 2 scenario) and found that:
Some of my albums were on my tablet but not on the card.
All albums were accessible on the tablet with the card removed.
Changes made to the title (number) didn't show up in the albums when I re-inserted the card.

I have read and re-read the manual and still find it confusing.

Can anyone explain how to achieve a single copy on my memory card and rectify what I have currently got.

Thanks
John
