Backstreet Boys - No One Else Comes Close
At first, I didn't even know this was a cover, as I didn't hear the original version until after I heard this. Said original was done by R&B singer Joe only a couple years before BSB's version came out. Honestly, I would love to hear both artists perform this song together. Joe did do a song with *NSYNC that's really good, so why not do one with Backstreet.
Britney Spears - (I Can't Get No) Satisfaction
According to WatchMojo, this is one of the worst cover versions ever made. I disagree. Maybe I just have bad taste. *shrug*
En Vogue - Hooked on Your Love
I'm not too familiar with the Aretha Franklin original, but I always liked this version. It's faithful to the Motown sound of the original, which makes it kinda stand out on an early 90s R&B album like Funky Divas.
I'll have to come back and link these later since I'm still a New Member and can't post links yet.
