I’ve written about Airy in the past. Eltima Software has upgraded their awesome little YouTube video downloader to 2.0, and brought with it a few handy features.

Airy 2.0 continues to make downloading YouTube videos even easier by adding the ability to download an entire YouTube playlist with a single click. I was able to download several playlists of music videos numbering from 15 to 40 videos with no problem at all. Downloading is the same as previous versions: you paste a YouTube video address into the Airy app URL bar, or use the included browser bookmarklet (my preferred method).

The update also adds the ability to pause downloads, so the next time you open Airy, the downloads resume automatically. Given that Airy downloads videos so quickly, this may seem unnecessary, but when you consider downloading a playlist with dozens upon dozens of videos, it can come in handy.

Airy hasn’t added any new formats that I can see. But you can already save videos as MP4, FLV and 3GP formats, as well as save only the audio as an MP3, so I see little room for improvement here anyway.

Airy 2.0 is a little faster, and a little more stable—though I never had problems with the older version to begin with. This is one of those little gems that I’m glad I have around. For years there have been plenty of YouTube video downloaders that were a pain to use, and usually stopped working after a few months. Airy has been around for a while, is not free, and is provided by a stable developer. That means it’s likely to be supported for the foreseeable future.

The latest upgrade runs on Mac OS X 10.7 and later. Previous Airy users can upgrade to the new version for 50% off, and new users can use the coupon code THGM-DSC at checkout time to receive 30% off the regular $19.95 price.
