personally, my ear training has only been successful/correct for songs ive heard numerous times.
as ive never heard this song/band before. it feels pretty right. the chorus is definitely right, the second part of the "pre-verse" section seems off.
an easy thing you can do to practice is have the line out from your bass/amp go into the microphone input on your computer. then set the microphone options to play the audio trhough the speakers. be sure to keep your bass volume down.
so effectively, you are playing your bass through the speakers.
From there, play the song on itunes or youtube, with headphones on, and play the song on the bass. you will know you are playing the write notes because you will hear no dissonance.
alternatively, you could write out the song in a midi format. which is what i do mostly.
