Yes, I have tons of music on my 1/2 gig chip. The trick is, format the MicroSD chip in the phone FIRST. Then copy your mp3 files to the chip. The formating is misleading because it is setting up folders that the LG 8350 expects to see. If you copy music to the MicroSD chip without those folders, the LG 8350 can not find the music because it is looking for the music folder.
