The whole does not freeze, but, eg, the playback time does. The first
lyrics get delayed because of this.

Seems sensible. I'll have a look at that code.

Sync was the reason I went with this method. I could try to sync to the
playback time, if this is precise enough, and if this is available where
needed. I'll look into this more.

Thanks
