you've been selected to be part of a music research dataset.
In this dataset, we collected your listening habits via last.fm API.
There is already a published dataset that contains the top-50 artists for a list of ~360,000 users (see http://mtg.upf.edu/node/1671 ). The new dataset were you'd appear it'll be similar to this one, but containing your listening history, anonymized.
In any case, if you prefer not being part of this new dataset, please let me know ASAP.
Thanks in advance!
