The Metroid series has always been known for crafting an effective atmosphere, there's just no other game that manages to capture that same sense of creepy isolation. Environment design plays a large role in this, but the soundtrack also contributes in no small way.

Considering that we just passed the 30th anniversary of Metroid, "Hip" Tanaka -- the composer from the original Metroid -- recently shared a message on Twitter about the series' landmark and music. Here's what he had to say:

I can only speak about the first Metroid game, but…

Around the time of the original release, I never got the impression the game was especially popular. However, as time passed and the internet came around, I became aware of just how popular it was, especially overseas.

The music in Metroid, I feel personally, was very different to the music in other games of the time; the sense of an individualistic sound design is very strong. I received some criticism, about the lack of melody, or how dark it sounded, but I felt I adhered to the tone of the game's story as I composed.

The fact that a piece of music containing only three notes has remained with everyone for so long is really surprising to me. I think it's because that even before music was in place, the game world of Metroid was fascinating. I have a lot of respect for the development staff from back then.

Knowing that even after thirty years the game is still supported by all sorts of people from around the world is a continuing source of courage for me as I continue to compose music, and gives me the confidence to believe in my own abilities, and push me forward.

From the bottom of my heart, I want to thank all the fans. The Metroid series continues to this day. I hope you will all continue to enjoy playing it.

Also, Tanaka put together a short music track mashing up various sounds and songs from across the series' history. Check it out here.
