Don’t Choose a DJ w/ “250,000 Songs”
I’d rather have a DJ with 1000 songs. Why? If a DJ had a fire at their house, they’d save their wife and kids first, and then their music.
It’s not hard to download 250,000 songs. I actually started out that way. I gathered every piece of music I could get my hands on.
It’s better for the DJ to gather a smaller, highly-curated list. They know these songs inside and out. They can quickly jump to best parts of the song, and skip over the boring parts. They find the best version of the song (there can easily be 20-30 DJ edits of popular songs), i.e. using a moombahton version of the song Milkshake always goes over well! The songs are properly categorized with beatgrids set (this allows music to sync up to light-shows). No person can do all this with 250,000 songs.
Understand, the above is true primarily when the DJ is mixing, mainly during the dance floor. I think it’s totally acceptable to build playlists using Spotify to play during ceremony seating, cocktail, and dinner (it still takes lots of time to curate this list).
