Spotify's online music studio now offers live collaboration

Spotify's Soundtrap is now more useful for artists who want to make music with distant friends. The online digital audio workstation (DAW) now has an opt-in beta for a live collaboration feature that lets multiple people make and see changes to a tune in real time. If you want to add a sick beat, you don't have to tap a sync button to ensure everyone hears it.

Another opt-in beta adds an (arguably overdue) auto-save feature to preserve your work. If you'd rather not participate in any tests, you can now leave Google Docs-style comments on tracks to guide your fellow composers.
