The verb 'gustar' (to like) is conjugated in two different modes, the subjunctive (gusta), and the indicative (gustaría).
To say it easy, the general difference between this two modes is that one describes reality as it is in fact, and the other describes hypothetical or potential realities. If you say me gusta, you will mention something that you like in deed. If you say me gustaría, you will mention something that may happen.
Hope this clarifies the difference.
