I needed a break from work and being there are so many cover songs on Youtube and the various sites that suck badly. Well I figured I would post up a few of my favorites that IMO don't suck. Most of these are acoustic guitar covers, feel free to post up other cover songs (I prefer unknown musicians or rare covers by well known bands)
A killer cover of outkast's "Hey Yea" song.
Mat Weddle of Obadiah Parker. (acoustic)

Most of these are from the video orginal poster's and some also have lots of other good cover songs as well as a few orginals in their profiles.
