I'd appreciate it if someone could check my sentences and tell me if there are more natural expressions. Thank you.

My favorite way to waste time is wathing TV shows and Youtube.
When I have nothing to do, I enjoy watching them and I lose track of time.
In particular, while I watch talent shows such as Britain's Got Talent on Youtube, I feel the time flies by. When a great singer performs, I can't help but listen to him/her sing other songs, and waste time surfing the Internet.
