The current generation of high-sensitivity (sub)mm-telescopes such as the IRAM-30m and NOEMA have allowed the emission from molecular lines to become a major tool for studying the physical, kinematic and chemical properties of extragalactic systems. However, we need to develop a detailed understanding of emission lines in Milky Way molecular clouds before we can exploit extragalactic line emission data to its full potential. With this in mind, the IRAM-30m large project “Line Emission to assess Galaxy Observations” (LEGO) aims at developing a comprehensive picture of how 3mm-band emission lines in MilkyWay molecular clouds depend on a variety of environmental factors. In this proceeding, I will focus on our recent detailed investigation of the W49 massive star-forming region published in Barnes et al. 2020 [1].
