If I Was Your Girlfriend - Prince
"Arnold, my love, why must I worship youand NEVER EVER tell?"

I also like the single version of 3 Dog Night's "Just An Old Fashioned Love Song" better than the album version because towards the end of the album version there was a part I didn't like that was wisely edited out on the single version.

I don't really need 7 minutes of "Private Dancer" by Tina Turner. Single edit of that's enough for me.

Single versions I also prefer over the album versions are Billy Ocean's "Carribean Queen" and "When The Going Gets Tough, The Tough Gets Going" because the album versions have long instrumental sections I've felt went on too long and the single versions also had a better flow to it.

Fleetwood Mac's "Oh Well," which on
Then Play On
is presented as a two-parter, the first part blues-rock with vocals, the second part an instrumental with an acoustic-classical-Spanish feel.

The Freshman by the Band Vervepipe. Lol I know its such an old song and kinda corny now, but I used to love it. I fell in love with the radio version and when I bought the cd there was a completely different version of the song on there. I was disappointed.
I totally hate it when that happens, I also hate it when the single version isn't available on iTunes.

Oh my god, I didn't recall it by name, so I just looked that up on Youtube and it took me right back to the 90s. Good song, loved it a lot back in the day.

"Naked Eye" by Luscious Jackson, unless I'm mistaken.
I recently downloaded something that sounded very different to the single I remember on the radio, and was a bit disappointed.
"One of These Nights" Eagles. The single fades out differently/sooner if I recall correctly, and I like it better.

"Make Me Smile" by Chicago

Who Are You? That last verse is horrible and it's a much better song without it.
"Worthington, we're being attacked by giant bats!"

The Doors' "Light My Fire."

"Pictures of You" by The Cure. The single version is tight and excellent; the version of Disintegration just goes on and on.

A lot of single edits are better because they get to the point. In that sense there's one song that comes to mind real quick and that's "Where It's At" by Beck. the album version is just so disjointed and the flow is messed up with all the starts and stops.
as for actual mixes, I prefer the single version of Superdrag's "Destination Ursa Major" to the album version. Not only are the guitars more delicious, but there's the Beatle-esque "Oooooh" during the second bridge that just makes the song perfect!
