Replying to Background music

I have to do this like video application thing and most of it is just me talking but it's kinda boring. So I was thinking about putting in like music in the background. Something not too distracting but that fills in the emptiness sort of. I'm honestly pretty shitty with this kind of stuff and don't even know where I'd look for something like this. My video has a pretty upbeat/light hearted mood so I'd like the music to not be super serious but still there, you know? So if anyone has any ideas on songs or just somewhere to look that would be sick!
