Playlist Sorting Using Source-Order Identifiers for Music Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing music apps, the order of songs in a user's download or collection list often differs from the original playlist order, leading to a poor listening experience.
Innovation Solution
The method involves adding identifiers to music information in a source music list to represent its order, allowing users to form a target playlist where the song order is consistent with the source list, ensuring songs are played in the intended sequence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If songs are sorted in download or collection list according to user clicking order or download completion time, then the download/collection operation is simple and fast, but the playback order becomes inconsistent with the original playlist order, degrading listening experience
Solution Approach 1:
The system performs preliminary sorting of music information according to the source playlist order before the user actually downloads or collects the songs. By pre-establishing the correct playback order in the download/collection list, the system ensures that when users play the downloaded songs, they automatically follow the original playlist sequence without requiring manual reordering, thus resolving the contradiction between fast download and order consistency.
2Ease of operation
If songs are sorted according to user clicking order, then the operation process is simple, but the user cannot listen to songs in the intended artistic or narrative sequence, reducing listening quality
Solution Approach 1:
The system copies the original playlist order structure from the source music list and applies it to the download/collection list. By replicating the authoritative source order rather than creating a new user-click-based order, the system maintains the artistic or narrative sequence intended by the playlist creator while keeping the operation simple for users.
3Reliability
If the system maintains original playlist order in target playlist, then the listening experience is improved, but additional sorting operations and identifier management are required, increasing system complexity
Solution Approach 1:
The system introduces an identifier (such as a sequence number or reference code) as an intermediary element that links the source playlist order to the target playlist. This identifier acts as a mediator that automatically carries the ordering information through the download/collection process, eliminating the need for complex sorting algorithms while ensuring order consistency is maintained throughout the system.

AI summary
Embodiments of the present disclosure provide an information processing method and a device. The method includes: in response to an operation acting on a source music list, obtaining a preset number of pieces of music information from the source music list to form a target playlist, where the music information in the source music list includes identifiers, and the identifiers are used to represent an order of the music information in the source music list; sorting the music information in the target playlist according to the source music list and the identifiers, so that an order of the music information in the target playlist is consistent with the order of the music information in the source music list. In this way, a user can play songs in a target playlist selected by the user in the order in the source music list, which improves the user's listening experience.
