(10 points best answer!) What are some great to sing for...?

So I'm a little stuck on ideas for a few youtube videos for me singing. And I have no idea what to sing, I was thinking of singing "White Horse" by Taylor Swift because I can sing that song pretty perfectly I think, and it's a slow song and I don't have many slow songs on my channel. But I was also thinking of singing "Just a Kiss" by Lady Antebellum. I can sing those songs pretty well I think. But I need more ideas. I also like singers like Katy Perry, Lady Gaga, Kelly Clarkson, Rihanna, Christina Aguilera etc.. singers like those. But I'm stuck on song ideas, and I can also sing a lot of P!nk songs, because her songs are kind of low. So anything like those. So if you could give me some songs like those i'd really appriciate it :) Thanks in advance :) No RUDE COMMENTS PLEASE!
