What are some good songs to sing?

I'm a alto but i can also sing saprano. I like songs that aren't too fast or slow. In the middle. I'm singing just for fun right now and i need some ideas. I have sang pretty much every disney song there is a kareoke version to on youtube so no classic disney songs please and i can sing pretty much anything but rock, rap, hip hop, and country. So like pop. I do like 80's music tho too and songs that are around now. thanks :)
