This is an ammendment to my earlier review. I found out that the SP50 does support variable bitrate MP3 files. I don't know what I did wrong the first time, but I ripped a few CDs using LAME's 192 kbps VBR setting (which uses bitrates from 192 to 320 kbps as necessary) and this time the SP50 recognized the files and played them. Unfortunately, I still heard the same "blips" that I mentioned in my earlier review. Not all songs had the problem, but when it did happen it was bad enough to annoy me. I ended up returning the unit and getting the SP90 instead. So far, the SP90 has had no trouble with any files I've thrown at it - VBR, 256 kbps constant rate, etc. Navigating the files is better than the SP50 (the joypad is much better than the SP50's buttons), but I liked the SP50's display better. The SP50 would tell you the bitrate, but the SP90 doesn't seem to do that.
So, I'm going to up my rating to 3.5/5. My last review gave it 3/5, so I'll rate it 4/5 to average it at 3.5.
