In this post I will cover how to analyse your songs and write their BPMs (Beats Per Minute) into your iTunes Database on your Mac.
First of all, you need djay for Mac. You can either get it from the AppStore or from the Algoriddim site. There is a free trial, but I’m not sure what the limitations are.
When you’re done installing, follow these easy steps:
- open the djay application
- click on ‘Library’ in the top menu bar (or in my case “Bibliothek”, since I used it in German)
- click on ‘Analyse…’ (or – again – in my case “Analysieren…”)
- press ‘scan’ or first choose a playlist
- get a cup of tea or coffee… a glass of water would be healthier though
- Close djay!
- Open iTunes and select all the songs you just analysed
Even when djay is done, you’re not! The problem is that djay stores the BPM data in its on database. Therefore we have to import the BPM data to iTunes.
You need an apple script to do this. Get the first one from here!
Wait for the download to finish (it’s just text, so it should be fast ) and then open the file. Your Mac will open it in the Apple Script Editor application. Here you can see what the script is actually doing – but don’t change it if you don’t know what you’re doing.
When you click on ‘Run…’ it’s just like a regular program. It asks you if it should replace the existing iTunes data (it’s just the BPM value). Just say yes and wait for the magic to happen. Leave the iTunes selection as it is until the copying is done.
There you go – sort your songs by BPM and listen to it from slow to fast or fast to slow.
