Fun fact: The Salamander 2 soundtracks are partially composed by Naoki Maeda, who would go on to become a major producer of DanceDanceRevolution songs.
Tetran & Death MK-III from Gradius V: The old Salamander boss music on steroids. And Universe is one hell of a way to start off the game. Impregnable Fortress, the rave-like music to the second part of Stage 7. Bonus points for an epic orchestral remake of Challenger 1985 as the song's intro. The awesomeness level is cranked up when it is Mickey Moused into the opening. It starts with the first few notes of the first stage theme from Gradius I, then kicks off into a high speed techno beat as you blast away enemy ships. "Cosmic Heroes" (Nemesis 3 MSX), "Into Hostile Ship" (Gradius II AC), "Mechanical Base" of Gradius III are all great examples. Almost any fortress theme in the series. Despite being played during the game's 6th level, it sounds like it's more fitting for a day at the beach. "Dead End Cell" from Gradius III is a very catchy tune. The video in question showcased all the variations from different ports (the NES version isn't as great, but it's still brilliant). Challenger 1985 is the most iconic song in the entire series. It always sounds like you flew to heaven or something, especially considering that most of the time, the entrances to these bonus rounds are welcome escapes from some very difficult levels. "Tears Began Gushing", the bonus stage music from Gradius II on MSX.
Maximum Speed plays in the high speed level, and it's very fitting for a level that goes very fast.
Newer-generation players, however, learned of the series' existence through Burning Heat! (Full Option Mix) from beatmania IIDX 7th Style and DDR 7th Mix (as a shorter, "3 Option Mix" version). Burning Heat, the Stage 1 theme, is pretty much the " Bloody Tears" of Gradius, since everyone identifies it with the series.The bulk of Gradius' most crowning songs accurately convey some sort of cosmic wonder.
