Until recently (couple weeks) I have used my Iphone to listen to songs that would pop in my head via Youtube that I haven't downloaded yet. Sometimes they were offical videos other times were those slide shows people would make themselves. But now doing a search on Youtube using my Iphone those types of videos are omitted. Doing the exact same search on a computer will give you offical releases and "home-made" videos. I did add a few videos to my favorites and they still work, but they will not show up in search results. Anyone else notice this?
