I'm having problems getting a third, different master track for Bass. I had issues with getting 3 different ones for guitar but it was quickly solved with a reload and retry.
I keep getting two Bridgeport Breezes as my master tracks and one is Amazing Maya. I've failed to get a third different one for a few times in a row and always ending up with 2 Breezes. So I am beginning to question if there even is 3 different master tracks for bass. Is there 3 and what is the third one called? I'm not looking forward to getting this same issue with drums. Does that have 3 different ones?
Guitar:
- Ballad of the Raider
- Kaitlin's Song
- So Epic It Hurts
- Walk The Path
Piano:
- The Line of Magnub
- Bork! Bork!
- My First Dance
- Cwik's Legacy
Bass:
- Bridgeport Breeze
- Amazing Maya
- Fears Come True
- Grandeur of the Strings
Drums:
- When We Met

- Morning Joe
- Stargaze
Violin:
- There are no master tracks and no challenges to complete
Edit: My luck turned and I've managed to master all instruments with a proper list of master tracks. I'm leaving this list here, maybe someone will find it useful since I could not originally find a list of all master tracks for every instrument by googling. To get the tracks you want, try saving before completing a challenge that gives you one. Reload until you get what you want. Might take plenty of tries for that last missing one. And subway stations really are the best for tips/collecting 25k.
Edit of edit: There are 4 master tracks for the 4 main instruments. Added.
