"She Looks So Perfect" and "Amnesia" made them the first band since the Beatles to debut its first three albums at No. 1 on the Billboard 200, riding a bright, hook-heavy pop-punk sound that leaned hard on the Warped Tour scene the members grew up idolizing. By Youngblood (2018) the band had traded gang vocals and skate-park energy for glossier synth-pop, but the pop-punk backbone never fully disappeared.
5SOS's official Facebook page named All Time Low as one of only three acts it listed under "influences," and the band's early run of gang-vocal choruses and radio-ready pop-punk hooks tracks directly onto All Time Low's mid-2000s Warped Tour sound.

Boys Like Girls was the third act named on 5SOS's Facebook influences list, and their radio-friendly blend of pop-punk crunch and power-ballad sincerity ("The Great Escape") maps closely onto 5SOS's own mid-tempo, string-laced moments like "Amnesia."

Mayday Parade was the second act 5SOS's Facebook page cited by name as an influence, and their emotive, melody-first take on 2000s pop-punk shaped the more heart-on-sleeve side of 5SOS's songwriting.
