Meaning of "Good For Me" by Aimee Mann

The lyrics of "Good For Me" by Aimee Mann depict a person who is aware of being in a harmful and toxic relationship but finds themselves unable to break free. The speaker acknowledges the destructive nature of the relationship by mentioning a waste of a smoke machine and the taste of dopamine being ruined. The repeated line "Good for me" signifies the internal conflict the person is experiencing – knowing they should leave but convincing themselves that staying is somehow beneficial. The references to alibis and digging tunnels out of Leavenworth paint a picture of someone trying to escape the consequences of their actions, while the imagery of being under rifle fire suggests a sense of danger and risk in staying. Ultimately, the person seems to acknowledge that the relationship is damaging, but can't bring themselves to leave, even though it is clear that it is not good for them.
