Error while trying to run colab notebook from readme.md

I get the error below when running the fastai2_audio.ipynb file.

`---------------------------------------------------------------------------
OSError Traceback (most recent call last)
/usr/lib/python3.6/tarfile.py in gzopen(cls, name, mode, fileobj, compresslevel, **kwargs)
1642 try:
-> 1643 t = cls.taropen(name, mode, fileobj, **kwargs)
1644 except OSError:

12 frames
OSError: Not a gzipped file (b'<?')

During handling of the above exception, another exception occurred:

ReadError Traceback (most recent call last)
/usr/lib/python3.6/tarfile.py in gzopen(cls, name, mode, fileobj, compresslevel, **kwargs)
1645 fileobj.close()
1646 if mode == 'r':
-> 1647 raise ReadError("not a gzip file")
1648 raise
1649 except:

ReadError: not a gzip file`

the URL of the dataset (https://public-datasets.fra1.cdn.digitaloceanspaces.com/)
seems to be no longer alive or is not public anymore.

Do you know which dataset is used there so we might find an alternative host?

That is my fault, for some reason that has been deleted. We're not that happy with the datasets anyway so would be good to set up a proper one.
