"Running out of Space"...
Not sure who sang it, but Cibryll likes the song a lot...
2020 song, likely...
I've found 2 songs with that name by 4oresight and Drexciya but I doubt they're the songs Cibryll likes because they're both instrumental.
As for songs, To Become God's Enemy is still my favourite RPG final boss theme. Also Mario Party DS had some fake "Anti-Piracy" trend which came with some original songs. Host Hoedown is actually quite good and is as worthy as "Piracy is no Party", the song that started it all.
