I discuss topics related to four-quark states of the ̀molecular quarkonium' type, i.e. resonances that could be considered as (dominantly) made from a heavy meson and antimeson. Of the so far observed resonances such picture is very likely applicable to the state X(3872), and I also discuss its possible relevance to the peak near the D*D̄* threshold in e +e- annihilation.
