I can't really see how this is even remotely proportionate, by any stretch of the imagination. What were these 24 tracks? A bunch of obscure Swedish Death Metal by all accounts. Is it likely that collecting these damages would make more profit than the sales of the tracks ever would? Maybe.
But, as she pointed out, she hasn't got $2m anyway, so they can't collect - it seems likely that the RIAA will just use the damages as a sledgehammer to bludgeon her into settling 'out of court' and out of the glare of publicity.
It makes me wonder what the jurors were thinking - awarding life destroying damages against a fellow citizen who is, presumably, an ordinary person, just like them. I don't think that I could do that, personally.
