My iPhone 4 has this annoying issue when playing a song. It freezes and locks up the iPhone while the song continues to play. The iPhone would not respond to ANY of the buttons for a good 30 seconds or so.
With the help a good friend, we investigated the issue and found something very unusual. (Btw, when I say we, he did 99% of the work).
Check out this great website that gives you a visualization of the many tracks that are used in the mashups. And, you can listen online too:

Album Art – The Culprit
Turns out the problem is not the mp3 but the album art that somehow got embedded in it. A few of the tracks had a JPEG album art file with embedded information from the original TIFF file. That’s not so much the problem. The problem was that the image size was 3744×3744. The image was taken with a Canon EOS 5D Mark II and the TIFF was created from Adobe Photoshop CS4 Mac.
How did we find all this info?
- Using a different MP3 player (MediaMonkey) loaded the mp3s and viewed their properties.
- Then saved the artwork to hard drive.
- Viewed that artwork in an image viewer.
Fix, is very simple.
Remove all embedded images in the mp3. Then, add a new image, with a smaller size.
I’m not sure whether the original mp3s had the large image issue or perhaps I accidentally added the large album art myself.
Lesson here, check your mp3s if your iPhone is slow to respond when playing certain songs.
