Basically, pick a super power that would give you no quantifiable advantage over anyone else.
Personally, I'm torn between selective wiping of my own memory (I could rewatch or reread anything for the first time every time) or having theme music play in my head and the heads of those around me. With an addition of the "KO!" sound effect if I ever knocked someone out, and hit/combo counters visible.
That'd be awesome.
Well, the thing is that by definition any "power" is going to be useful in some context over someone who doesn't have it. Now granted it's easy to come up with ones that are of of such limited use that they seem kind of pointless, but that isn't the same thing. Case in point if you could project music into someone's head you could do a lot of things like that, even if it's just driving people insane (in a very literal sense). Selective memory wiping could be useful
to counter "killer memes" (old science fiction concept) and simular things, not very likely, but it does give you a potential advantage over someone who doesn't have it.
The closest I could come up with is the abillity to change a soft drink into another soft drink of the same type. Basically the power to say transmute say cola into any other kind of cola, like RC cola into Coke, or Coke into
Pepsi, or whatever. Of course that still means you have the advantage of never having to endure a brand of soft drink you don't like, unless you just really hate Cola or Orange Soda or whatever you've got out of hand.
This also reminds me of one of my favorite Xanth novels (I used to be a fan) where most of the powerhouse Magicians and Sorceresses in that world are defeated quite easily by some guy who has the minor magical talent to create a line of sight between two objects.
