描述

An Apple Music playlist (~99 songs) I was trying to download kept crashing with the following error:

[•] Collating...
  [•] Inquiring tracks...(failed: [Cannot read properties of undefined (reading '0')]) 
 [i] An error occurred while processing the query (Failed to collect playlist tracks)

After a lot of trial and error, I narrowed the problem down to a single track: "Watch - Nosaj Thing": https://music.apple.com/us/album/watch/1608121372?i=1608121589

Removing this single track from the playlist allowed the entire playlist to download successfully.

研究方向
Investigate the track parsing logic in the Apple Music module. Look for where response data is accessed with index [0] without checking for undefined. The crash occurs on a specific track (Watch Nosaj Thing). Check if the track has missing or malformed data. Examine the code around the 'Inquiring tracks' step, likely in src/providers/apple music.js. Consider adding input validation and graceful error handling for such cases.
