Add a link to this site in the app
The app should have an easy to find link to this site so people who use the app can vote for songs and features. I can garuntee that 95% of yousician users have no idea this place exists. Also just refining this site could be a great step in the right direction like being able to say name of song, name of artist, and genre when adding song ideas AND an email to inform users WHY that song might be unable to be added due to licensing. Knowing why is a lot better than just not having it.
