25 Best Cover Songs of 2008 has a nice little selection. my favs:
- calico horse's take on "idioteque" (sweet acoustic/vocal arrangement)
- flaming lips covering the who
- radiohead doing neil young (pers fav, as i was 15 feet away when they performed this... magical moment)
- gnarl's take on "reckoner"
- max vernon doing katy perry
not saying these are the best, but they are good.
that oak ridge boys boys cover is indeed great.
