The second one is Doctor Who series 4!
Movie Soundtrack - The Mummy theme by Jerry Goldsmith.B2B.
The first one sounds sci-fi ish. And it seems like a lot of people here know it. So, I'm going to say Doctor Who, because it seems like a lot of people know it. And it sounds like something that would be from the show. The second one, really not sure. But, with the acoustic guitar sounds, it's got to be Western themed. I'd say maybe, 80s or 90s, because shows back in the 1960s or 1970s may not have had that kind of high quality sound
