Hello, Which is the advertised figure?
I suggest you don't think too much about this "advertised figure"; it's misleading and no longer relevant.
The advertised figure (mentioned by jpianomantech in his (or her) post in January 2014) was originally provided when the iPod first came out. It was based (as Niel mentioned is his post) on songs being encoded at 128Kbps, and the songs being an average of four minutes long. This means that some songs could be three minutes long, while others could be five minutes long. It's not the length of individual songs, it's the average length of all the songs combined.
So - when the iPod Classic first came out, the theoretical maximum number of songs was approximately 40,000.
However, since then, the Apple store and most other digital music sources encode the music at 256Kbps and this means that a song now uses twice as much storage space as it did when the "advertised figure" was first promoted. This reduces the theoretical maximum number of songs to 20,000. In addition to this, if you use 256Kbps encoding for music from your own CDs and the average length of all your songs is longer than four minutes, then the maximum number of songs is reduced still further.
My personal library has a mixture of music at 128Kbps, 256Kbps and even higher Bit Rates, so the maximum number of songs I could put onto a 160GB Classic will be far less than 40,000. The average length of all the songs in my library is 4 minutes and 48 seconds.
So the maximum number of songs I could get on my (now broken) Classic is less than 20,000.
But before you think of using a lower Bit Rate, just remember that lower Bit Rate will mean reducing the quality of the music, while the higher Bit Rate will mean better quality.
If you have more music than you can fit onto your iPod, the solution is to use Smart Playlists to automatically remove music from your iPod (for example, once it has been played) and then put it back again after a set period of time has elapsed. This means that at any time, not all your music will be on your iPod thereby reducing the space needed on the iPod itself. One last point about this: since Apple's largest capacity iPod is currently 128GB (in December 2017), the chances are that when your Classic fails, you will be replacing it with a lower capacity device. To deal with that, I suggest that you start trying Smart Playlists now.
