Add BPM to songs in iTunes – BPM Tapper

Yesterday I explained how to add BPM data to iTunes using beaTunes. That works well, it’s free and can batch process your entire library. But I also explained that it sometimes gives weird results. When this happens you can manually assign BPM to individual songs by simply tapping to the rhythm.

Today I found a very cool (and free) app for Mac called BPM Tapper. You basically play a song in iTunes and tap away at the rhythm for a few seconds. Then click a button and it adds the BPM to iTunes.

Simple. Accurate. Cool.

Here’s what the developers say about it:

This free little buddy is used to get BPM’s for your songs into iTunes. Just tap the big button along to the beat of the music and a precise BPM will be given to you. Just tap and all will be revealed. This is your start into a world of perfect BPM playlists.

And here’s a video that shows it in action:

I downloaded it and have been playing with it all day. And I love it.

Get it at the developers site or from the Mac App Store.

BPM in iTunes – How to add BPM to songs in iTunes with beaTunes

There are basically two ways of creating playlists of songs that match your running pace, and one requires you have Beats-Per-Minute in iTunes:

  1. You can manually drag in songs by hand
  2. You can automatically add songs using Smart Playlists

If you’re like me and have several thousand songs in your iTunes library, option 1 doesn’t sound too appealing.

I started manually adding songs myself, but after a while it does become a drag. I either ended up just picking the songs I listen to most often, or started going through them in alphabetical order but got bored before I finished the A’s.

So I set out to find a way to do this automatically.

To do this, you need to know the rhythm or cadence of each song. In iTunes that means knowing the Beats-Per-Minute, or BPM. Now, I’m sure I’m not using the correct terms (rhythm and cadence might be completely different things) so if you’re a musician, please forgive me. This is how I understand it best and I’m not really interested in semantics.

Why do you need BPM in iTunes?

Having accurate BPM values in iTunes for all your songs will allow you to do Smart Playlists quickly and easily. I explained roughly how to do this when I posted my first running playlist in JoggerTunes.

Basically all you need to do is set BPM as one of the rules in the Smart Playlist to the range you want to run to. Then just add other rules like genre, maximum time, artist, etc. as you wish.

So how do we add BPM in iTunes?

There are several ways, some free and some paid. We’ll explore several in the future, but for now I want to explain how to do it for free and automated.

I did it using a software called beaTunes.

beaTunes is a paid app by Tagtraum Industries, but they offer a 14 day trial that allows you to add BPM values to your entire iTunes library. Just download the app, install and run it. It’s fairly simple and self explanatory, but here are the steps (or you can check the detailed description on their site)

  1. Start beaTunes
  2. It’ll ask if you want to analyse the library. Click yes.
  3. In the Analysis Options dialog box that appears, tick Estimate BPM and Replace existing BPM if you want.
  4. Click Analyse and wait.

And I do mean wait. My iTunes library has just under 14,000 songs and it took several hours. Not sure exactly how long it took to process as I did it at about 6pm and left it all night. It had finished all my songs when I woke up the next day.

It worked well, however, I did find a few discrepancies with beaTunes putting different BPM to songs I had repeated in my library. I spoke about this before. Overall though, it’s been great creating random playlists using BPM in iTunes.

This is a Mac solution though, not sure about Windows options yet. There are a lot of possible solutions for both Mac and Windows here.

BPM in iTunes – Conflicting results

Getting beats per minute, or BPM in iTunes is a pain in the butt.

I’ve been playing with different applications and widgets to help me do this, but I’ve had very discouraging results so far.

I’ll give you an example of how screwed up my BPM in iTunes are.

At some point I must’ve ripped the Romeo + Juliet Soundtrack CD twice into my iTunes Library. Not sure how or why, but it’s happened a couple of times so I’m guessing I wasn’t that organised back then. However, the fact that I had 2 identical albums in my Library proved a good test for the software I used to automatically calculate and insert BPM values to my songs.

Well, after running the software to add BPM in iTunes, some songs match exactly, which is what you’d expect given they’re the same song. But some are completely different. It’s just ridiculous.

How can the software calculate different BPM in iTunes for the same song, ripped from the same CD.

For example, Local God (track #2) has a BPM of 111 in one album and 56 on the other one!

Then Little Star (track #12) has a BPM in iTunes of 153 in one album and 77 in the other one. Similar with Pretty Piece of Fish (track #4), with 183 in one and 91 in the other one.

The strange thing is that most of the other songs have exactly the same BPM.

I’ll keep testing different ways of getting the BPM values into iTunes and will post my findings here on the blog.

(UPDATE: I found a better, and free way to add BPM in iTunes)
