Clipping hasn't been an issue for me. You might need to fiddle with where the song loops to find a suitable point, but it should work just fine.32000 Hz seems to create clipping in the brstms from what I've seen. Though some of the songs weren't of my own devising so the creators probably did something silly in encoding or whatever. Some of them are just generally long though; no amount of compressing will solve that.
Loop points are easy enough with basic understanding of sample points and arithmetic.
And you'd be surprised how much it helps. I managed to cut off about 10MB just by compressing a few of my longest songs.
