Check the eligible pool
Kodi documents reuse when Party Mode has a small library. If rules reduce the available selection to a handful of songs, a repeat does not automatically indicate a decoding or playlist failure. Inspect the eligible pool and its approximate total duration.
Match the mode to the session
For a casual private listening period, repetition may be acceptable. For a fixed presentation or an approved event running order, random replenishment may not fit. Decide the requirement before broadening rules to include music you intentionally excluded.
Review exclusions directly rather than observing a few random choices. A song not heard during a short session may still be eligible. Keep the pool rule and a few included and excluded samples so the result can be checked again later.
Choose a deliberate next step
If the pool is too small, add appropriate authorised material or choose an explicit sequence for the required duration. Do not promise that a random mode will produce a particular order or a repeat-free window without evidence from the actual setup and requirement.
Questions answered
Does a repeated song prove Party Mode is broken?
No. The official guide documents reuse in small libraries.
Should I remove all exclusions to avoid repetition?
Only change eligibility when it still fits the audience and permitted use; otherwise choose a more suitable sequence.
