I give a brief account of current topics in description of exotic multiquark mesonic resonances with hidden heavy (c or b) flavor, the so-called XYZ states, in terms of hadronic molecules and hadro-quarkonium systems. Also discussed are the recently observed hidden-charm pentaquarks including additional ways of producing them in experiments.
