iTunes’ Smart Playlists are fast way to view types of media in your library. Here are some cool examples from Lifehacker of ways to organize and clean up your iTunes library quickly using Smart playlists.
Automatically Create the Perfect Workout Mix
As we’ve pointed out before, the best music for exercise tends to be between 120-140 beats per minute. You can automatically generate playlists that fit that criteria. First things first, you need to get the BPM added because iTunes doesn’t do it automatically. While it’s pretty old software, we likeMixmeister BPM Analyzer as a free way to add BPM to your iTunes library automatically. Just drop your music library folder into BPM Analyzer and wait for it to do the work.
Once you’re done, you can generate workout playlists easily. Make a new smart playlist (hit the big “+” in the bottom left corner and select “New Smart Playlist”) with this rule: BPM is in the range of 120-140. It won’t be a perfect list (some not-particularly energetic songs still fall in the 120-140 BPM rule), but it’s a quick way to make a near perfect workout mix with no work.
Clean Out Old Podcasts
If you’re anything like me, you’re a podcast hoarder. These days, I just use Downcast to listen to podcasts, but at one point they all filtered through iTunes. How many? Well, in my case I had 1,239 podcasts—that’s 27.28 GB of podcasts just sitting on my hard drive wasting space.
If you want to clear out all those old podcasts, just make a smart playlist with this rule: Media Kind is Podcast. Then hit the + sign and add this rule: Plays is 1. This means you’re shown the podcasts you’ve already heard so you can quickly delete them without futzing about in the podcasts tab.
