Soundiiz always tries to transfer as many matched tracks as the destination allows. If the destination limit is reached, Soundiiz may create multiple playlist parts, stop adding tracks, or display error 106.

Current playlist track limits
The values below are the operational limits currently applied by Soundiiz when creating or updating destination playlists.
These values may be lower than a platform’s theoretical limit when Soundiiz applies a safety limit for reliable playlist creation and updates.
Limits can also change when music services update their applications or APIs.
What happens when a playlist exceeds the limit?
For some destinations and transfer operations, Soundiiz can automatically create several numbered playlist parts.
This behavior is currently supported for:
For other destinations, Soundiiz stops adding tracks when the maximum playlist size is reached.
Tracks beyond that point may appear as Not found in the transfer report because they could not be searched for or added after the destination limit was reached. This does not necessarily mean that the tracks are absent from the destination catalog.
What is Soundiiz error 106?
Error 106 means:
This error usually appears when you try to add tracks to an existing destination playlist that has already reached, or is about to reach, its maximum size.
How to complete the transfer
If the destination does not support automatic playlist parts, you can:
- Transfer the tracks to a new empty playlist.
- Split the source playlist into smaller playlists.
- Transfer a smaller track selection.
- Remove tracks from the existing destination playlist.
- Choose another destination service with a higher playlist limit.
Even when a playlist is below the limit, the number of transferred tracks can be lower when some songs cannot be matched in the destination catalog.
