Well, I've searched and I've searched all over for better quality tracks of the Sailor Stars Character Single Karaokes. However, the Track 4s (and the Track 3 for the Nagareboshi he Karaoke) all have some sort of pop and cracks to them. I've been searching high and low for better quality for the karaoke tracks that's more than 160kbps and only the Mercury and Mars Karaokes had those. If anyone has these karaokes from the singles in better quality, let me know.
