Fatal Spotify plugin error - Bad gateway

When importing a lot of music with Spotify plugin, sometimes I get a "Bad gateway" error which is fatal. With quiet imports I can't resume the import and have to start again.

It would be great if this error could be made non-fatal. Maybe that the song could be retried later?

Problem

Running this command in verbose (-vv) mode:

$ beet -vv import -q -s folder

Led to this problem:

spotify: Searching Spotify for '[Blue Archive] Theme 99 (Onsen/Hotspring Event Lobby BGM) artist:Salieri AS Beta'
Sending event: import_task_created
error: Spotify API error:
{
  "error" : {
    "status" : 502,
    "message" : "Bad gateway."
  }
}
URL:
https://api.spotify.com/v1/search
params:
{'q': '[Blue Archive] Theme 99 (Onsen/Hotspring Event Lobby BGM) artist:Salieri AS Beta', 'type': 'track'}

Here's a link to the music files that trigger the bug (if relevant):
