I discovered KOL recently and absolutely love "Because of the Times". I snapped up their other two releases, but still believe BOTT to be their best by far. As such, I noticed that the singles from this album included some non-album tracks. In "Fans" case, it's "Woo Hoo". This is certainly a good song and along the lines of quality with any other songs on BOTT. The real gem in terms of b-sides for the BOTT-era is "My Third House" from the "On Call" single. This is an excellent song which I highly recommend. The other single of the era "Charmer", has a remix of "My Party" which is just OK. Kings of Leon have a lot of b-sides so I would have to believe a Rarities/B-Sides album will come eventually (a la the Killers "Sawdust"). If your a modest fan, I'd say wait for it. But if your really into KOL, I would pick up "Fans" and "On Call" for sure.
