Songs with similar chord progression

One feature I think would be nice is,

  1. if you for example choose a song from the database hookpad can show songs with similar chord progression. Instead of go to the database,click in the chords, then find other songs with that chord progression.

  2. If you create a song from scratch, and add a chord and then other chords, hookpad could show other songs using that same chord progression as you build your chord progression.
