Magic resistance is a specific term referring to MR.
The effect of MR is to create an area around your body that has little to no ambient magic, which is why it works on almost all spells. The song of magic is concentrating the ambient magic in the environment, therefore even people who have resistance are more easily affected than before.
This is a different concept than saving throws and art. Increasing your saving throw is making your body and mind tougher or more able to dodge the affects of magic attacks directed at you. Increasing your art improves your skill and "accuracy" at wielding those spells. Neither of them is attempting to modify the ambient amount of magic nearby.
Some might argue that having their MR reduced is a good thing. xxx reduction to magical resistence is a thing thats been requested on items by the playerbase. Only Sorcs and Necro's actually desire MR. Well except for a dwarf barb I know of that is a complete n00b. (thats right, I said it.)
