Music Player Windows 8/RT

Alright... I need an app suggestion. I have my music stored on Google Music online, where I use GMusic on my Surface and the website on my laptop to listen to my music. However, I also have my music stored locally on an external HDD for my laptop, and on a Micro SDHC on my Surface for those moments I don't have an internet connection. Considering XBox music still frustrates me completely with its performance and lack of of an offline listening mode, I need a better local music app. Tried Multimedia8 (think thats what its called) but thought that was horrible, as it wasnt designed to be a music player. So essentially I'm looking for an iTunes/Windows Media Player clone that is designed to play locally stored music. Any suggestions/does anything exist for RT?
