Tune down ½ step (tuning, low to high: Eb, Ab, Db, Gb, Bb, Eb)

Note: I hear some D's (4th string, open) a little here and there (or is it
just my imagination?) and I don't know if it's intentional or just mistakes,
there is no pattern to my ears. Maybe you can help me out if you think that
I am wrong.
