-- Marketers, take note. Adults' love of social networking sites is driving away teens. "Although their love of being online shows no sign of abating, the percentage of 15- to 24-year-olds who have a profile on a social networking site has dropped for the first time - from 55% at the start of last year to 50% this year."

-- Grooveshark's iPhone app, which will soon be submitted to Apple for approval, received a good review at CNET blog Digital Noise. The app faces two issues. One, as Digital Noise has pointed out, is the obvious conflict with Apple's role as a seller of download content. Many are questioning if Apple will approve apps that would limit the appeal of iTunes. Grooveshark falls into that category, as does Spotify. The second issue is the legality of the services. Spotify has obtained the proper licenses for its services. Grooveshark currently operates in a legal gray area and is currently dealing with a lawsuit brought by EMI. Will Apple impose a licensing litmus test on hopeful apps to weed out possible legal issues? (Digital Noise)

-- The Tennessean looks at the decline in album sales that coincides with the sudden rise of bands playing albums in their entirety at concerts. The Pixies are going on a "Doolittle" tour. Judas Priest has been playing "British Steel" start to finish. Van Morrison, Steely Dan and Aerosmith are doing similar shows. In Nashville, Bill Lloyd's band The Long Players recreate an entire album every time they play (next up is The Beatles' White Album). (The Tennessean)
