Hey! This is a normal concern and for myself, I have made some prioritizing. Nr1. Always, choose the right track for the moment Nr2. Choose the right transition (where do I set the cue and for how long will I play the track. Cut, short, long mix?) Nr3. Play the next track in Key? (Bar/Party=Not important, Club=More important, House tech, deep…= Always) Nr4. Using effects? Bar=No, Club=Build ups coloring loops (to get more energy), House Tech Deep=Nice ‘n’ smooth coloring of transitions and lesser parts.
This is not cut in stone, but makes it easy to choose the right gear and what I need to focus on. In a bar, you need to be more people oriented and perhaps chat a little with the customers in between tracks. To choose not to use effects and easy short transitions will give you that time and people will see you as a relaxed and friendly DJ 🙂 . Stress is always around the corner, so giving yourself the time to choose the next track and have time to spare will give you a nice experience in the Booth.
Keeping the key/tempo and making perfect transitions may sound impressive in a mix you make for listening to, but in a live situation, especially in bar or private event, that’s usually not the way to go. Changing tempo and genres is usually what gives the best reactions. Don’t be afraid to take some risks, and just make sure the next track starts with something highly recognizable, and you and the guests will have a good time.
