40 years have passed since the first molecular detection outside our Galaxy. Since then, our knowledge on the distribution, kinematics and composition of the molecular material in the extragalactic ISM has built up significantly based not only in the carbon monoxide observations but also in the nearly 50 molecular species detected. In particular, line surveys have been proven to be excellent tools to study the chemical composition in the nuclei of galaxies. Such studies have been favored by the increasing instantaneous bandwidth of current mm and sub-mm facilities. I will summarize the highlights of extragalactic molecular spectroscopy mostly focusing in the molecular line surveys published in the last few years. Similar studies towards Galactic sources are important as reference to understand the extragalactic ISM. Galactic templates will be key in the nearby future taking into account that facilities such as ALMA will provide us with an spatial resolution in nearby galaxies similar to current resolution towards the center of our own Galaxy.
