So it all looks good, but I can't help thinking that there might not be room in the market for yet another vaguely social amateur music recommendation site. Purevolume started off looking quite promising too, but now suffers massively from rich-get-richer charts, and it looks like artists must pay to get on the front page (where most of the traffic comes from). The quality of encoding has also dropped unbearably low since it got more and more popular, as you can tell if you compare my brother's old band (The New Lev Yashin: purevolume, myspace) or his friends (Burnout In The Capital: purevolume, myspace, Stories and Comets: purevolume, myspace).
In the case of 15 Megs of Fame, it looks like the charts aren't totally ratings-based, so hopefully there'll be enough churn in there to keep good artists bubbling to the top. I wish that the ratings system led somewhere though, like the T-Shirt design ratings on Threadless lead to actual T-Shirts, maybe the song ratings on 15 Megs could generate the track-listing for a monthly compilation CD that I could subscribe to?
Anyway. 15 Megs of Fame: great looking site but needs something else, I think.
