Yes. There are videos in Youtube that can show you how to download it if needed.
Sadly, there is no such app that allows you to do this.
Now YouTube launched its own music streaming service - YouTube Music. It allows free users to listen to music online. If you have a Premium account, you can download YouTube Music for offline listening. YouTube Music is compatible with the iPod Touch. If your iPod Touch supports the YouTube Music app, you can play the songs on your iPod Touch directly. If not, you can try Macsome YouTube Music Downloader, It allows you to download YouTube Music to MP3, and then you can sync YouTube Music to iPod.
You can find animes such as Inuyasha on iTunes. If you can't find what you want, download and convert videos from youtube using Zamzar.
You can download videos off of itunes.
