What are some songs to sing?... (PLEASE ANSWER)!?

So I have a youtube channel, but I'm stuck on ideas for songs. I was thinking of singing "White Horse" by- Taylor Swift because I can sing that song pretty perfectly I think. But I need some more ideas. I like singers like Rihanna, Christina Aguilera, Kelly Clarkson, Lady Gaga and Katy Perry, and some songs of Lady Antebellum. So songs like those artists I love to sing to. But I have no idea what to sing from there songs. If you have any songs that are popular right now please list them :) And I was also thinking of singing "Just a Kiss" because I can also sing that song pretty well i think so um yeah.. but please list a lot of songs, and also the artists names please :) Thanks in advance :)
