Leased beats are written for nobody in particular. Your song has a specific verse length, a specific hook, an intro you don't want — and the instrumental doesn't know any of that.
Basic Editing covers the fixes most songs need: shorten the intro, extend the second verse, add another hook, cut the outro. Flat rate per song, quick turnaround.
Advanced Editing is a different animal. When a track needs its arrangement genuinely rebuilt — sections rewritten, elements swapped, structure reworked from the ground up — that's hourly work and we'll scope it with you before committing to a number. We'd rather quote honestly than start a flat-rate job and discover it's a six-hour rebuild.
