Files are 408.0 KB & are .mp3.exe (with the exe icon). AntiVir found WORM/Fontra.C during download, which is the same as the Delf.ATB worm that Aaron suggested months ago.
Worm/Fontra.C - Full description
One person also downloaded a Bitdownloader file & got hit with this worm.

These ones show up in my search as "song title Bitdownloader", again with the exe icon. The ones I found were 220.5 KB. Antivir ignored them, AVG Antispyware found Trojan.Obfuscated.en.
There are some other really nasty little .mp3.exes of 228.0 KB & these show up with TR/Drop.VB.ME.1, TR/Drop.VB.ME.20. Can't find too much info about these but they seem to be much harder to get rid of than the worm.
