-- An economist ponders reasons why rap albums are song long. A great explanation for the prolific nature of rappers comes in the comments section: "Rap songs require less effort on the instrumentation side. Since beats are almost exclusively electronic, they can be made in high volumes at relatively low costs." Of course, "relatively low costs" is hard to define for hip hop productions. The costs vary widely. Later in the comments comes more good insight: "Rap artists, in one sense, are just taking advantage of the the space available to them on a CD. They presumably don't have much invested in the 'tradition' of the LP because the LP was dying out just at the time their genre was being born." (Marginal Revolution, via Digital Audio Insider)

ISPs would encounter very real costs in dealing with informing - and eventually disconnecting - repeat infringers. (paidContent UK)

Only two titles in the Top 100, U2's "No Line On The Horizon" and Dave Matthews Band's "Big Whiskey & The Groogrux King," have sold that many LP units since being released. Neither, however, came close to Pearl Jam's first-week LP total.
