"Believe in Myself - Sonic Adventure 2" is a high quality rip of "Believe in Myslf" from Sonic Adventure 2. It was originally uploaded to the GiIvaSunner channel on February 19, 2016.
The rip is unedited until the lyric "I wanna fly high" at 1:01. The "fly high" parts of that line are sung using the audio of "Snow halation" (which also has "fly high" in its lyrics). After this point, the rip becomes a mashup of the advertised track and "Snow halation", with the latter's vocals over the former's instrumental.
At 3:11, the "Believe in Myself" lyrics come back, until the "I wanna fly high" line, when "Snow halation" comes back.
- The video description's catchphrase is a reference to a scene in Sonic Adventure 2 Battle where Eggman says to Tails, "Because you just told me, fox boy!" It should be noted that "Believe in Myself" is the theme of Tails in Sonic Adventure and Sonic Adventure 2.
