Keep in mind that digital media releases are separate to physical media releases in MusicBrainz, so the tracks can be named entirely different between different releases, even if they share the same Recordings.
As such, I tend to stick closer to what the digital media distributor says rather than look at how tracks are listed on physical media releases. Of course, for digital releases distributed through multiple channels (say, iTunes + Bandcamp + Amazon + Spotify) it would probably make sense to look at all (or at least multiple) of these channels and see whether they all agree on the extra title information (e.g., do all the track titles have "(salsa)" in their name on Spotify too?). If 3/4 list something, then I'd go with that. If it's 2/4 one way and 2/4 another way (or every store lists it differently), then I'd pick the "best" of these (and maybe I would glance towards physical media release track lists here).
