I'm using DLNA network in my home to show PC contents on TV that support DLNA. (Don't get confused, It's not like VGA or HDMI cable. TV gets files from PC and plays them, doesn't show screen of PC) You know, it's boring to just listen music if there is no video. I want to visualize music. My TV doesn't support it.

I'm looking for software which can generate this type (or this) videos from music files. Or source that I can download ready made ones of popular music.

Anyone can help me?
