Why is it that adding impurities to a compound lowers it's melting point?

More molecules to interact with one another?

I'm thinking now that it probably has to do with the ability of a solute to disrupt a tightly packed structure (which is the reason why a solute lower the freezing point...

Yes. Also, freezing point and melting point are the same thing.

doesn't it have to do with lattice structures being disrupted, should raise the boiling point as well I believe, correct me if I am wrong.
