I’m sure it’s bad form to write a review then follow up with a completely contradicting one, but I can’t figure out how to edit a review I’ve already made. So, this will have to do.
SizzingKeys is definitely a 5-star app for me. I’ve tried a bunch of other ones—Synergy, Bowtie, Alfred, etc.—but none of them are as feature-rich as SizzlingKeys. As far as I know, none of he others will let you fast forward incrementally through songs, engage and disable shuffle or loop, plus all the other standard functions the other ones let you do (paid version features).
I was complaining about the app in my previous review as it was PAINFULLY sluggish, but the more I thought about the more I realized it was only since I had upgraded to Mountain Lion, and that other apps were sluggish too.
THEN I realized that most of the one that had become sluggish around the same time were all set as startup/login items in my system preferences. Suppressing these apps at startup and launching them right after made them as good as new! Including SizzlingKeys!
I’ve been using it for almost a week without issue. It’s back to the near-instant responsiveness I remember from when the app was packaged as a preference pane.
I love this app again!
