Currently there is only ogg and wav support
Although these are the most common ones, a lot of other formats are supported, so it's probably better if you say "Currently there is no support for MP3" ![Wink ;)](https://www.sfml-dev.org/forums/Smileys/default/wink.gif)
Good point.
Here is the list of formats in the faq--I don't know if there are any more:
ogg, wav, flac, aiff, au, raw, paf, svx, nist, voc, ircam, w64, mat4, mat5 pvf, htk, sds, avr, sd2, caf, wve, mpc2k, rf64
