Finally, it must be noted that white people are acutely ashamed of the gateway song because it proves that he/she was completely unaware of a genre of foreign music until exposed by the distinctly unauthentic mainstream media. White people would prefer to be exposed to "world" music from browsing non-chain record stores, study abroad programs, and non-white friends. Bonus would be a combination of a musical "discovery" while falling in love with a foreign person. However, since these more authentic methods of "discovering" "world" music are not always available, gateway songs are a necessary evil for the average white person.
Guy 2: Dude, that song sucks. It's just a gateway song. They have way better songs.
