I found iSing to be a real hoot, as did my children, although they all have yet to tread the waters of personal embarrassment and upload their own dulcet tunes. And that highlights one of the beauties of the program: You can vote as often as you wish without once having to upload a song of your own.

I also found it entertaining to troll through the "Worst" lists and find some of my worst favorites. (No lie, there's a character on iSing who makes seem like a potential Grammy nominee.) My one disappointment--and what I think limits the value of the app--is how few times a month you can upload a song without having to pay a fee. Sure, you don't want people uploading a song a day for a month, but allowing only one song per month may be too few opportunities for fun. Considering the national attention span, the limitation may make people forget about iSing. After all, even got more than once a month to play on American Idol.
