Even from the cover art...
...you can tell this release was not done fully with the band's consent. The guitar on the cover is clearly a Les Paul-style, when the Ventures are universally acknowledged to be associated with Mosrites. Also, the other reviewer seems to be on point that this is a re-branding of another hits package available here. This is done with other bands here as well (there are about 8 DRI hits releases here that are nearly identical save the track sequence). Oh, the songs a decent enough versions, but there's certainly no need to re-download them, unless you're trying to be an MP3 completionist, in which case, I tip my hat...to eMusic for finding such a great customer...
