Sellix 

Sellix is an e-commerce website that is incomprehensibly terrible. Used by demented merchants (mostly minorities), Sellix breaks frequently, and will most times (if not all the time) kill more than half of your braincells.

Buyer: Hey, do you have a sellix I can use? I don't want to buy off a strange website.
Merchant: I do. Allow me to link you.
Buyer: I'm having issues with the website, could you assist me?
Merchat: Nigga that's your issue. Deal with it yourself, or buy off the sketchy website.

song selling 

Song selling takes place when a singer-songwriter earns money in exchange for the rights to use his or her original music, often to a (more) famous, or up-and-coming, recording artist.

If a singer-songwriter has written a catchy song but seems to fall short on vocal or instrumental ability, a listener might say, "you should sell your song." Hearing this can be extremely disheartening for singer-songwriters, especially those who are still developing their talents, or have not yet enjoyed their fifteen minutes of fame.

Why does song selling even exist? Any band or singer who is worth their weight can write their own songs.
