Typically your request will be played within 10 minutes of requesting any given song. However, there are number of factors that can cause it to be played later.
Timing – Spark DJ runs and acts like a live DJ – mixing songs and taking requests when it sees fit. If you don’t see your request get taken right away (and you have no negative votes) be patient and Spark DJ will find the perfect fit for your request! Spark DJ is also required to follow music licensing guidelines which restricts certain songs at certain times.
Voting – SparkDJ looks at votes to determine if it is a right fit for the crowd. If your request finds its way to the top – be on the lookout for it get played! If you find your request is making its way to the bottom, head back to the Requests tab to remove your request and add a new one.
