What songs do you like are in another language? I personally love “Sen no Yoru no Kotoe” by Aqua Timez for the anime Bleach in Japanese which I come across a week ago on YouTube, but I find myself constantly listening to it. Unfortunately, I cannot Japanese to appreciate the lyrics.

By another language you mean other than English?

I have so many (both local Filipino songs and Japanese anime ones like yours. XD)
For now I’ll pick these two.
Musouka by Suara - This the full OP of the anime
Utawarerumono. I’ve been listening to it because I’m currently writing a short anime-style fantasy story and it songs like this that get me in that sort of mood.
Nescafe by Parokya ni Edgar - Yes, as the name implies, coffee is involved and it’s actually used in a commercial promoting the titular brand.

Strangely enough though, it stands well on its own as a sort of novelty song Parokya ni Edgar is known for.

Coffee and relaxation aren’t an irony, they are a paradox! XD
That and I just love hearing this line:
Tumambay muna tayo diyan sa tabi - A rough translation would be “Let’s just hang around in the corner.” Loitering in sari-sari stores (they’re sorta like mini general stores) and karinderias (street-side eateries) is a common past time for Filipino college students (including myself

).
