Occasional pause

[issadarkthing]

I notice after some time, song randomly paused for like 1 seconds. This only happen when it has played a few songs. Currently, I'm not able to reproduce the bug.

I met several panic around the time you post this issue, but after I switch to lrc file parser and resync by offset, I haven't met such panic yet. Probably it's related.
