Work types should only be used on works that specifically match the chosen type (not every work needs to have a work type!).
- Beethoven's Sonata Pathétique is set to "Sonata", but its first movement should not have a type, since it's not itself a sonata (nor does it fit any other existing work type).
- Schubert's Winterreise is set to "Song-cycle", while its first part, Gute Nacht is set to "Song".
- John Williams' soundtrack for Star Wars, Episode V: The Empire Strikes Back is set to "Soundtrack", but the Imperial March should not be.
Add disambiguation comments only when two (or more) works are similar enough to be confused, not just because they have the same name. For example, there's not much use in adding "Scorpions song" to Blackout just because other artists have songs called Blackout. On the other hand, a translation of a work with the same name as the original might deserve a disambiguation to make it more obvious, like with Dreams come true ("Japanese version") by BoA and the original Korean version.
