Today Spotify added gapless playback, probably the most wanted feature among classical fans. If your desktop hasn't been automatically updated, you can get the new version here.
A few examples to showcase this great new feature:
Stockhausen's monumental work for six vocalists and six microphones, Stimmung. Over 70 minutes long, in 51 tracks, now with no gaps in between!
Live albums sounds so much better without gaps. Check out the last three track from Grateful Dead's Europe '72 Vol. 2, one of the most exciting encores ever.
Concept albums are now presently properly too, from What's Going On to Deltron 3030, from The Ninth Wave (the second half of Hounds Of Love) to The Downward Spiral, all those annoying gaps are gone for good.
If the short pause between the third and fourth movement of Beethoven's fifth Symphony made you wanted to bang your head on the desk, rejoice now, those days are gone and gone forever. Listen to The Fifth, or any symphony smoothly as one whole piece of work now. If you don't know where to start, check out my previous post: ABC Classic FM's Classic 100 Symphony.
And yes operas! Finally you can listen to a Wagner piece as three hours of contentious music without interrupting of any kind (provided you've turned off the phone and Twitter). Go search for an opera, or pick up one from my Wagner, Puccini, Strauss, Britten or Mozart playlist.
Electronic music/DJ mixes also benefits greatly from this feature, follow @afront and check out his blog for tips on that.
All album examples are linked to Spotify. Try it for yourself and look forward to your recommendations.
