Here's some little tests I made. All the cards were bought at Best Buy so I assume they are not knockoffs.
Tried the Wiki's .UZE and data file on two SDSC Sandisk 2G and it works fines on both. One of them though has very occasional hiccups in the BG.
Tried the t3k.uze from this post and level data provided on the wiki (+5.0.11 bootloader) on the same 2G cards and it works fine.
Tried t3k.uze on a Sandisk SDHC 32 GB 30 MB/s card and the data file (+5.0.11 bootloader) is found but BG severely glitches.
Tried t3k.uze on a Kingston 64GB SDXC card and the data file (+5.0.11 bootloader) works flawlessly. Note I had to create a 4G main partition in order to format it in FAT32 (was exFat by default).
Hope that helps.
One thing I noticed is that one of the lead instrument in the title if very faint now. Is it possible that one or more waveforms were removed or changed?
With space I have saved from recent optimization I could include an SD card test function in the code. Warn if the card is too slow to stream the webs.
My ears don't work great so I never noticed the lead instrument on the title being faint. I did notice the "play" sample seemed to have disappeared at some point though. I'll try investigate this.

That would indeed be a very nice feature! Btw, for reference, the instrument in problem is that tubular sounding patch that starts at 14 seconds in your youtube video.
Things I maybe could do now with extra flash space
ADPCM audio compression to fit extra samples
Bonus Levels
Extra songs
From optimizing/changing-things/refactoring I have been able to get 2140 bytes free right of this moment.
Next thing I am working on tonight is new meet the enemies screen for the attract mode. Here is my awesome MSPaint skillz showing off how I envision that looking.
Extra audio channels so music and SFX can play at same time (new 8 channel audio system)
This caught my attention! 8 channels would be pretty impressive. What would this entail? Would this involve an upgrade to the UB OS/ROM? Would each channel be able to play samples?
