Conversation so far:
What have Fall Out Boy left as a legacy?
Sugar, We're Goin Down as possibly "the most listened-to emo track of all time".
Was this created while they were still together?
In 2009.

Question: Did they have any other hits that did well?
Self-contained rewrite: Aside from, "Sugar, We're Goin Down," did Fall Out Boy have any other hits that did well?
