Data Insight
The credit table tells a clear story: DeLonge and Hoppus each wrote roughly half the catalog, with Travis Barker almost never holding a writing credit until the 2003 self-titled album. Songs were typically written by whoever sang them (DeLonge sang his, Hoppus sang his), making the writing split a near-perfect mirror of the vocal split. Barker's first credits appear on the self-titled record, where several tracks are attributed to all three members, reflecting a more collaborative dynamic that emerged after years together.
