My highest-scoring song on vocals is "Paradise by the Dashboard Light", my signature performance here has been "Come Out and Play" for the longest time (high official [but not actual] difficulty, 100% and probably high leaderboard spot), and my signature performance on Facebook is "Seven Nation Army" (tied for #1).

low rider: rank 149 out of 270.000
walking on the sun: rank 98 out of 270.000

My best performance is Low Rider.

Well that was my best guess. If it's not that then I have no clue how these so called "best performances" are arrived at. It is starting to seem arbitrary.

And assigning my "best performance" to Need You Tonight on PRO keys is more than just a little bit insulting. It is VERY insulting!

Unlike on the "My Gameplay" page here, the dashboard seems to be picking the song where you have the highest percentile rating (highest star rating?) on ANY song (not just on your most played / best instrument). Which, as SkyP1e notes, is often going to be "Need You Tonight" on Keys or Pro Keys. It doesn't tell you on which instrument you were playing when you earned that best performance, but I'm just guessing that's how it came up with that answer for me. And yet, why not "Free Bird"? That would be awesome! It's not my signature performance under "My Gameplay" either (that would be "Debaser", my 7th best vocal performance if you sort by rank percentile, but a very reasonable pick).

Sorted by percentile:

Song...................Instrument..Rank........... .....Rank %-ile..Score.....Level..Stars
Free Bird..............VOCALS......241st / 55,699...99.6..........149,900..X.......6.92
Need You Tonight..KEYS..........723rd / 33,800...97.9.............4,139..X.......7.87
Need You Tonight..PROKEYS.....562nd / 22,184...97.5...........15,018..H.......5.99

Sorted by Stars:
Song...................Instrument..Rank........... .......Rank %-ile..Score.....Level..Stars
Whip It................VOCALS......7,101st / 54,915..87.1..........104,662..X.......14.15
Imagine...............BASS.........13,883rd / 95,865..85.5...........17,002..X.........9.67
Imagine...............VOCALS.......5,636th / 70,143..92.0..........130,508..X........8.99

I did have 2112, now I have Charlene. Im guess for drums, since im ranked #1 on it (with a ton of other people).

My signature performance on the forums is Dance, Dance on vocals, and my signature performance on Facebook is Rainbow in the Dark on vocals
