Yes! Some DSPs like TikTok, Apple iTunes and Amazon Music support track previews and you may specify a Preview Start Time per track when you upload a new release. Additionally, you may add a Preview Start Time to tracks on existing releases via the Edit Content flow.
Currently, Stem only supports 60 second preview durations. If the Preview Start Time falls within the last 60 seconds of a track, the Preview will end when the track ends. For instance, if the total track duration is 3:35 and you set the Preview start time at 3:00, the Preview length will be 35 seconds.
