About the correct use of at them or in them Hello, I was discussing with my friend, because this: What should be the correct sentence: That made me interested in them or that made me interested at them. I'm confusing because I know see people use: "Look at him" ~ so for this reason it confuses me!

Hello I want to make a question about the correct using of is or are! I'm always asking me when I want to use "The lyrics are/is really cool" But don't know what to add if "is" or "are"! Thanks in advance for your help!
