I'm not sure how widespread the problem is, but it seems that the server sometimes (for no apparent reason) will list the same alias twice, even with no difference in capitalisation, spacing etc.

The artist I'm referring to is Marina and the Diamonds whose aliases are listed as:
*Marina & the Diamonds
*Marina and the Diamonds
*Marina and the Diamonds

Since there's no "Merge" feature for credits, it's also unclear how to resolve the duplicate (since they appear to have no difference whatsoever)

It's not a major issue obviously, just a quirk that I thought I should point out.
