    Very useful post. Thank you very much! From my side I can recommend one more free program for home and office: Interactive Calendar (http://www.csoftlab.com/Calendar.html). It is very interesting daily planner with an ability to show scheduled appointments directly on your desktop wallpaper.

    Hello Pranav,

    I think I have a great addition to your list, it is the relatively unknown software "123 convert YouTube to MP3". I found it last week and it's easy to download songs with (no url copying) and completely free!

    As far as I can tell there are no limits or hidden fees.

    regards,

    Niels
