What I like to do is set up my playlists/crates based on music genre/ event type. So my gigs primarily range between schools, weddings, conferences and private events... So for example, I will have a playlist called "Party Bangers (Clean)" So everything i put in this playlist or crate will be popular party songs, but also clean. I do this with everything so I have a twerk playlist, a twerk (clean), line dance, slow dance, 2000s hip hop, EDM, R&B, R&B (clean), R&B (sex) etc. I have a playlist called "bid dinner" (I use this playlist for college parties, but typically frats and sororities) or "cocktail hour black" (I use this playlist for dinners and events where its background, chill vibes music primarily for black audiences.) So I may put together a crate for one event, but then I just keep it running with similar type songs, and know what playlist to use based on the crowd in front of me. Songs can go in multiple playlists As for new songs, the easiest way I use to remember to play them.... when I go to Serato, I typically organize by BPM, so I will sometimes change the sort filter based on song order. Since I just added the newly downloaded songs to the playlist/crate, those should be either at the top or bottom, this is how I refresh myself live on what new songs I downloaded. I sometimes do this with my entire library, just sort based on song order, and your newest ones will be at the top. Take a look at the BPMs and make a plan live to integrate it within your set. Hope this helps!
