wording could be improved, surely.

this would be to link genre names which are commonly confused with each other, such as brostep and dubstep, edm and techno, metal and screamo, or as I recently found, contemporary classical and modern classical (confused name second). just think about what your dad (or more generally someone not familiar with the genre) would probably call the music you listen to... 😂

such a relationship could possibly help with searches and perhaps suggest alternatives while entering tags.

this could alternatively be partly fixed with "search hint" genre aliases. however I think a relationship would be better, as it actually links the genres together (making browsing easier).

examples of possible wordings:

• modern classical is not to be confused with contemporary classical
• brostep is often (mistakenly) called dubstep
• screamo should not be confused with metal
• techno is not the same as edm
