The new generation of streaming music services like Spotify, Rdio, and MOG have more music than you could consume in a lifetime. But how much of it would you really want to listen to?

There’s no shortage of great roundups and reviews showing the pros and cons of each service, but they rarely talk specifically about the different music you can find on each. They’ve all built impressive catalogs, but it’s nearly impossible to tell from casual browsing which artists and albums are exclusives for each.

Fortunately, both Rdio and Spotify offer powerful developer APIs, making it simple to compare the two. (Sadly, MOG doesn’t offer an API, so isn’t included.)

For this test, I needed a large set of popular, well-loved albums to test. I used the top 5,000 albums from Rate Your Music, the quirky 11-year-old online community dedicated to rating and reviewing music. These albums span all genres, from klezmer to chiptune, with a total of 2,282 different artists across 70 years of recorded music.

It’s been a good year for all things Twisted. Eagle Rock released a welcomed bombardment of quality Twisted Sister reissues and special editions over the last year (perhaps the best of the bunch were the Club Daze reissue and the five-disc DVD set of live performances over their entire career, From The Bars To The Stars); a documentary by Andy Horn is in the works; and now the band celebrates Christmas in their own Twisted way with a performance at The Best Buy Theater in NYC on Saturday, December 17.

And with a new solo album (Dee Does Broadway) on its way out and an autobiography to come, Twisted Sister vocalist Dee Snider is keeping busy with his own career. However, he was kind enough to discuss the musical impact of Twisted Sister’s legacy.

So you’ve bought iTunes Match, which gives you access to shiny new 256kbps AAC versions of your audio files. But by default your iTunes library is still packed with your old files. So how best to upgrade all of those old files, in place, to the new versions?

Here’s how to do it—keeping in mind that you can only do this after you've completely turned iTunes Match on:

Make a Smart Playlist Create a Smart Playlist with the following attributes:

Bit Rate is less than 256kbps
Media Kind is Music
Any of the following are true: (to create this conditional, option-click on the plus button in the Smart Playlist window) iCloud status is Matched, iCloud status is Purchased

Att Apple numera säljer avsnitt av tv-serier på iTMS är en revolution inom tv-världen. Enligt Blog Maverik kan detta vara räddningen för kabel-tv ("Network TV").
