I'm tired of not being able to use Aero's Snap feature on Spotify's window in Win7 and Win8. This AutoHotKey script will perform a fix to the window on load, as well as any time you attempt to use a Win+{Direction} combo on the Spotify window.

FixSpotifyAeroSnap.ahk

if WinExist("Spotify") or WinExist("ahk_class SpotifyMainWindow")
{
 WinGet, Style, Style
 WinSet, Transparent, OFF
 WinSet, Style, % Style | 0x40000 | 0x400000 | 0x800000 | 0xc00000
}

FixSpotify() {

 if (Title = "Spotify") {
  WinGet, active_id, ID, A
  WinGet, Style, Style, A
  WinSet, Transparent, OFF, ahk_id %active_id%
  WinSet, Style, % Style | 0x40000 | 0x400000 | 0x800000 | 0xc00000, ahk_id %active_id%
