for anyone looking to replace the samsung music player for whatever reason, here you go! it's the standard android 1.5 music player and it is a little less laggy, but also less polished looking. i'll be sticking with samsung's just because it looks cleaner to me, but the stock player may be better for those that multitask with the music playing as you should experience less device lag. to install this you will need to download either "astro" or "apps installer" from the market. you will need to set your B2 to allow unknown apps installation, then transfer the apk to your memory card from your pc. Once that's done find the file with either of the two apps i mentioned and use them to install it. enjoy!
