Dragging along the music progress bar generates lag

[Cyriod]

In the Editor, if you drag the progress bar instead of clicking it to jump through the music, it causes a big lag depending on how far away you are dragging it for.

• Only happens if the music is currently playing.
• Music still plays during the lag.
• New beatmap

Seems to be because of spammed animations

not sure gonna investigate later
