Well, I'd say 128kbps is reasonable enough quality (minimum to sound good).
Average album length is somewhere between 40-50 Minutes, 1 Minute of 128kbps is 960kb so if we do some rounding and come out with 45MB per album.

32GB MicroSD after format will probably have 29GB available.
29696/45 = 659.9

So roughly 660

320kbps is coming in at about 2.5 the file size so at that quality around 264

FLAC you'd probably get 65 Albums.

1GB = (appr) 1,000MB. A decent quality "album"? 100-300MB.
Now take out that calculator :p

Let's face it, you want 320kbps. That means you're looking at, on the safe side, 250 albums per 32GB card.

Depends really, if it's just something to listen to on a commute through my low-mid range headphones then 128kbps will more than do.

If it's on my Cowon D2 though with some nice headphones then I'll take 320kbps and depending on the album I'll even go for FLAC.

A lot of people would be hard pressed to tell the differences between 128 vs 320 (although it does depend on the album)

About half the people get it wrong.
