Tab-Complete

Several tasks go into first verifying and then annotating tabs.

1. Scrape the tabs and lyrics from the online sites
2. In the tabs, separate the chords from the lyrics
3. Align the lyrics and tabs

At a high level, our general approach to finding structure in a (now completed) tab is:

1. Find the choruses (contiguous lines of lyrics that are repeated)
2. Find the verses (contiguous lines of chords (that do not overlap with choruses) that are repeated)
3. Find intro, outro, and bridges (all contiguous lines that do not overlap with choruses or verses)
