You've got a good start to something; take two steps back, consume and digest the feedback you're getting, then use it to better your approach.
First make a notes app that people love. This will be harder than you think. Once you've done that and have enthusiastic users it will be much easier to move into other areas.
Hasn't this been the Evernote Recipe For Disaster?
Better to slightly misuse/expand an existing know term like projects or notebooks to cover more than it does now, than to invent a new term that covers all the meanings that apply, but whose meaning is initially unfamiliar to people.
E.g. "my way is da best, you should do WHAT I SAY"
Though the one I listed is the first lemma.
Also, it's inconsistent. Youtube organizes channels because it is a video app and people coming from tv immediately understand. Spotify uses tracks because it is a music app and the term track has been synonomous with song since probably the first record player.
Its a good try, but just mashing up two concepts into one causes confusion
