I've been using them for large music albums for many years. With the right hardware and software, you can achieve over 90 minutes. To do this, you MUST enable overtubning in your software and increase the maximum overflow threshold, because that's the only way any disc above the standard size can hold more music. I use Nero BurningROM. I could record up to 92 minutes of music on a disc and read it through my car stereo with no problem! (Your mileage may vary for different players) All in all a fantastic product.
