Having troubled looking for a soundtrack or background music for your presentation? or You seems to watch silent movie or video of your creation? Hard to find for a creativecommon audio file that fits your work? or simply, you love music? Try UJam!
I was once looking for a music that fits my presentation in my class and I was so afraid to just download music from the net or use soundtracks from copyrighted audio files. I also had problems with my students when they ask me what should be their background in their movies when I tell them that they are not allowed to use music or soundtrack which are creativecommons and not permitted to use by authors. Good to find something like this.
