Urbano moves like hip-hop: a tagged MP3 to write to, an untagged WAV once the licence is settled, and a trackout for the mix with every element as its own full-length WAV from bar 1. Latin pop and regional Mexican sessions deliver the same trackout from the tracking day, plus the chart or arrangement the band played from. Ask for the trackout by name rather than "stems", which can mean grouped submixes. Lyric sheets travel with the vocal, and the title and the artist names should be spelled with their accents in the file names and the metadata from day one.
