AI Generation Prompt
DJ Playlist Duration & Song Count Calculator
Overview
A professional-grade, browser-based utility designed for DJs to plan, manage, and calculate the exact timing of their sets. The tool allows users to input track durations, calculate the total length, and account for transition times, ensuring performances fit precisely within allotted event slots.
Core Features
- Dynamic List Management: Add, remove, and reorder tracks via a clean, intuitive table interface.
- Real-Time Duration Totals: Auto-summing functionality that provides total duration (HH:MM:SS) instantly as tracks are added.
- Transition Buffer: A global setting to add a fixed amount of seconds (e.g., 30s) per transition, automatically factored into the total time.
- Song Count Tracker: Tracks the total number of items in the list to help visualize set density.
- Average Track Duration: Automatically calculates the average length of tracks in the list to help identify if the set is moving too fast or too slow.
- Clean Print/Export: A dedicated print view to save or print the final set list with timing details.
UI/UX Design
- Aesthetic: Strictly light-mode, modern SaaS look. Uses high-contrast typography, soft drop shadows for cards, and rounded corners (border-radius: 8px).
- Primary Colors: Professional palette consisting of clean whites (#FFFFFF), light gray backgrounds (#F9FAFB), vibrant blue accents for primary actions (#2563EB), and soft gray borders (#E5E7EB).
- Layout:
- Header: Contains the tool title and a summary bar (Sticky Top) showing "Total Time", "Song Count", and "Avg. BPM/Duration".
- Main Area: A table interface where users input track names and duration (MM:SS).
- Actions: Floating action buttons (FABs) or clearly styled primary buttons for "Add Track", "Clear All", and "Print".
- Footer: Absent (per requirements).
Technical Constraints & Directives
- Architecture: Purely single-file (HTML/CSS/JS). No external frameworks required (Tailwind CSS CDN is acceptable for styling).
- State Management: STRICTLY IN-MEMORY. No use of
localStorage,sessionStorage, or cookies. The state must be contained within a JavaScript array object. - No Popups: Use hidden
divelements or custom modal overlays for any alerts, warnings, or prompts. - Browser Security: The app must function within a sandboxed iframe. Ensure all external links have
target="_blank" rel="noopener noreferrer". - Performance: Ensure smooth interaction. Input fields should auto-format as users type timestamps (e.g., automatically inserting colons for MM:SS).
- Responsiveness: The table layout must collapse gracefully on mobile devices, turning into a card-based list layout for easier mobile editing.

Frequently Asked Questions
Everything you need to know about using this application.
How do I calculate the length of a DJ set?
Calculating a DJ set length involves summing the duration of all tracks and accounting for the typical transition time between songs. This tool helps you input each track's individual duration, automatically summing them to provide a total set time in hours, minutes, and seconds. By including an optional 'transition time' buffer, you can also account for the time spent beatmatching or crossfading between tracks. This ensures that your set list fits perfectly within your allotted performance slot without running short or over.
Can this tool help with set programming and energy flow?
While this tool primarily focuses on track count and time, knowing the total duration is essential for maintaining consistent energy flow. By tracking the total song count and time, you can better organize your library into 'warm-up', 'peak', and 'cool-down' sections. This data-driven approach allows you to verify that you have enough high-energy tracks for your main set time and enough background material for your warm-up slots. It is a vital step in professional set preparation that prevents rushing or gaps in your performance.
Is my playlist data saved in this application?
No, this is a privacy-first, client-side application that runs entirely in your browser's memory. For security and privacy, your playlist data is not saved to any database, cookies, or local storage. Once you refresh the page or close your browser, all input data is cleared automatically. We prioritize your privacy by ensuring that no tracking or persistent data storage mechanisms are included in the tool, meaning your sets remain entirely private to you.
Why use a DJ set planner instead of manual calculation?
Manual calculation of track times often leads to errors, especially when dealing with long tracklists. This tool automates the math, allowing you to add, edit, or remove tracks instantly while watching the total duration and song count update in real-time. This saves valuable time during your preparation phase, allowing you to focus on track selection and mix programming rather than arithmetic. It provides a clean, accurate visual interface to manage your set's timing and flow effectively.
