audacity freezes when song change happen when delete key is being pressed deleting items off playlist

[themusicgod1]

Steps to reproduce
1) have a large playlist(haven't tried it with small ones yet)
2) press and hold delete key while audacity is playing near the end of one song so that it continues to delete track after track with enough songs left on the playlist that it's still deleting when the song change happens
3) when song ends, instead of jumping to the next song, window becomes completely unresponsive, no audio is heard.

desired result: not freezing, skip to a next song.
