Music on My Hand

I bought the SAMSUNG mp3 player almost a month. I'm always thinking to have a good mp3 player c/w recorder on my hand, since i am a music lover, it's a MUST or NEEDS in my life. Finally, i got mine, a simply & nice mp3 player and c/w recorder. But compare with the picture above, I think it's IPOD NANO, i really cannot afford, so a Samsung normal mp3 will do, it cost me RM199. But so weird you know, i think this mp3 cannot stand the heat, whenever i jogging of course will put inside my pocket right? after 4 songs, the tempo of the song going slower than the normal. Sigh... maybe Samsung product is like that, I wont complain cuz RM199 sure not the best, but i still love it.
