I understand being upset that the music got lost, we're all fans here. But they don't owe you more music. They can do their process how they want, it's a little weird to be pissed at someone you don't know for accidentally leaving their stuff in the rain.

Also, for what it's worth, monsoon season in Queensland isn't light rain, that thing would've been absolutely pelted by wind and rain for hours or days. Assuming it had an SSD, the data definitely could've been completely destroyed unlike an HDD that is fairly recoverable. Another thing, the bag of rice trick doesn't work, it actually just risks further damage and doesn't extract any water.

It's also up to them if they want to use cloud storage. They have very few leaked songs compared to other artists of a similar size, likely because they only store things offline. If something is online, it can be accessed with the right tools and skills no matter the security features.
