90210 appears on Rodeo, Travis Scott's debut studio album released in 2015, and features singer Kacy Hill. The title takes its name from the Beverly Hills postcode, with the long, two-part track moving from a hazy, reflective opening into a harder second half. Clips from the song have circulated for years in fan edits and short music posts, where its opening atmosphere is easy to recognise from only a few seconds. Its continued use comes from that distinctive mood, which still signals a specific era of melodic trap.
