One thing that I regret not mentioning in my interview, because I only started thinking about it after reading some other users interviews is that, think of it this way
The best song to send to TISC could be a song that isn't a favourite genre of anyone, something slightly obscure, or something so generic it would appeal to everyone.
For example, my favourite genre is folk and perhaps I want to hear more folk songs.
Someone sends a folk song, but I have thousands of other folk songs that I can compare the song with, because I'm heavily invested in that genre. So if you're reading the interviews and aiming to get 12 points from someone, remember that it could also be a trap
