Playlist instead of band/dj - help!

Hi everyone. I'm getting married in 2 months (eek!) and we have decided to create our own playlist for the evening instead of hiring a band/DJ - we're both passionate about music and would rather have control over what's being played. I'm confident that we can curate a really good playlist, I'm just not sure on the logistics of it. I just wondered if anyone else is doing this and how you're going about it? Any tips would be greatly appreciated!
