Maybe I didn't explain myself very good...
 
What I meant is not to play an artist or album.
 
What is mean is that your search, is filtering also by artist and album name (and not only by song name).
 
So for example when I search for Foo Fighters, it shows me all songs from Foo Fighters (even though they have no "Foo Fighters" in their song name).
 
What I think would be nice is to search *only* the song name for whatever string you put. So if for example, there is no song named Foo Fighters, the previous example would return blank (instead of all songs from the band Foo Fighters).
 
Thanks

Introduction
 
With the introduction of Alfred v2.0, the built-in iTunes mini player is now the only way to interact with my iTunes library in Alfred. However, I would prefer to quickly search for and play songs without entering the mini player first. Therefore, I created Play Song—a workflow designed to make playing songs in iTunes extremely quick and convenient.
 
Download
 
Download Play Song (latest)
 
Usage
 
Play Song enables five keywords which allow you to search for and play songs in your iTunes library.
In order for Play Song to function properly, it requires access to assistive devices. You can enable this for Alfred via the Security & Privacy pane of System Preferences.
 
Playing a song   To play an individual song, use the playsong keyword. Songs whose names match your query will populate the list of results. Choosing a song from the list will play that song once.   Playing an album   To play all songs from a particular album, use the playalbum keyword. Albums whose names match your query will populate the list of results. Choosing an album from the list will play all songs from that album (ordered by track number).   Playing an artist   To play all songs by a particular artist, use the playartist keyword. Artists whose names match your query will populate the list of results. Choosing a artist from the list will play all songs by that artist (grouped by album).   Playing a genre   To play all songs within a particular genre, use the playgenre keyword. Genres whose names match your query will populate the list of results. Choosing a genre from the list will play all songs within that genre (grouped by artist).   Playing a playlist   To play all songs within a particular playlist, use the playplaylist keyword. Non-empty playlists whose names match your query will populate the list of results. Choosing a playlist from the list will play all songs within that playlist (according to playlist order).

@James You are right, opacity must be less than 100%.
I made screenshots for anyone else having trouble with the blur effect.
I hope this helps!
 
 

 
 

 
 

 
 
 
(Restart Alfred after setting Blur Amount)
 
 

NOTE!! From Alfred 2.4, the blur setting is in Alfred's Appearance > Options. You won't need to use the defaults writes, but it's still marked as experimental. I plan on implementing the native Yosemite blur at some point and make this an official feature.
 
This is and always will be a hack, but I'm adding a defaults write preferences item to set the background blur of a window. This will allow you to have nice transparent themes but still readable over busy backgrounds.
 
There are a few important caveats with this:
It uses a private OS X API which means it may stop working at any point outside of my control I may take this feature out if it causes general instability and will ignore any moans of "put it back" It disables the 'Fade in Alfred Window' option because these don't play nice together It slows things down lots on slower Macs This will work in OS X 10.9 Mavericks from Alfred 2.3 onwards! To use this hack, quit Alfred and his preferences then type this into Terminal:
 
OS X 10.9 Mavericks:
 
defaults write com.runningwithcrayons.Alfred-2 experimentalBlur -int 5
 
... the value can be anywhere from 1 to 15 for different blur radius levels, set to 0 to disable.
 
OS X 10.8 Mountain Lion and below:
 
defaults write com.runningwithcrayons.Alfred-2 experimentalBlur -float 3.0
 
... the value can be anywhere from 1.0 to 5.0 for different blur intensity levels, set to 0.0 to disable.
 
Here is what you should see:
