Merging isn’t the way to go on RouteNote ⛔
RouteNote allows for ISRCs to be reused across the same user account! However, once a UPC has been submitted to RouteNote, it is unfortunately unable to be reused on other releases, including replacements.
But, there is still a solution! You can create a new release and upload all chosen tracks into one release.
Please ensure that the Publishing section lists all composers and lyricists featured on the release.
Please note! If your old release remains live on stores, then Spotify has a feature that will attempt to link your tracks and combine the streams: this is called track linking.
If you have any further queries, feel free to get in touch with us!
