To get a dj or just use Spotify?

Hi everyone! So our wedding is three weeks away and for the longest time we have been thinking of just going without a DJ for our outdoor intimate wedding, but we’re now thinking of possibly getting a DJ and wanted to see if anyone had chosen to just DIY there own music with Spotify and a speaker at their wedding and how did it go? Did you regret it? Did it make the day a lot more difficult to manage? I would love to hear your comments and opinion on this. Thanks!
