Auto-Mix (Smart Ordering for Playlists and Albums)

[milocraft]

Overview:
Auto-Mix allows users to automatically reorder songs in any playlist, album, or song collection for seamless playback. It intelligently arranges tracks based on musical and tonal characteristics, creating smooth transitions that feel curated by a professional DJ or music producer.

Core Functionality:
Users can enable Auto-Mix on any playlist or album and select preferred ordering criteria. The algorithm dynamically sequences songs to create a cohesive listening flow, with adaptive transitions and graceful fallback behaviors when perfect matches aren’t possible.

Ordering Criteria Options:

• Smooth BPM Transitions: Gradually adjusts tempo between songs to maintain rhythmic flow, with adjustable BPM tolerance thresholds.

• Musical Key & Chord Structure: Matches or harmonically relates songs to avoid tonal clashes.

• Vocal Attributes: Sort by vocal density, vocal gender, or instrumental vs vocal balance.

• Genre & Intensity: Groups by related genres or energy levels for emotional or energy-based progression.

• Other Filters: Song length, release date, artist continuity, or user-defined “mood curves.”

Fallback Strategy:
When ideal transitions aren’t possible, Auto-Mix applies fallback tactics such as soft crossfades, key-shift blending, or contrast-based sequencing to preserve flow and interest.
