Songtrust is a publisher, so we don't collect audio information. We also do not distribute your songs or track them on streaming platforms (expect for where royalties are collected). We only provide you with the ability to search your songs on Spotify because we extract your ISRC's from Spotify's database.
If you're not sure what ISRC's are, or why we strongly ask for them, start here.
If you don't have recordings, don't worry! All you need to work with Songtrust is your compositions. But if you're curious, here's the difference.
