A question about the lyrics not showing

Describe
1. There are more than one song in the playlist
2. The lrc field of the first song in the list is an empty string
3. Other songs have LRC fields and this field is the URL

Problem
- All the songs can't show the lyrics

The problem I found in Hermit-x, but I think it's a APlayer question.
Aplayer won't try to load the lyrics file.
