What are some popular songs to sing ? (please answer 10 POINTS!)?

So I'm stuck on what songs I should sing for my youtube channel. I know some popular songs are "Just a Kiss" by- Lady Antebellum, and "Edge of Glory" by- Lady Gaga, and I personally like "Edge of Glory" better, and I can sing it easier... but I was wondering if they are are any really great popular songs that are out now?.. And also just some popular songs to cover in general. Thanks in advance :) SERIOUS ANSWERS ONLY PLEASE :)
