// In C/C++, the idiom (sizeof(arr) / sizeof(*arr)) is often used to get the length of an array.

// I wrote this bookmarklet because Amazon has ended Linux support for downloading MP3s,
// and now I have to download songs separately through Amazon Cloud Player.
// This bookmarklet helps a bit with this, but it's far from perfect.
// When a list of songs is shown in Amazon Cloud Player, it clicks the song checkbox and
// the download button separately for each song, while waiting a few seconds in between songs.
// I encountered the issue that I cannot download more than a few songs simultaneously;
// the rest will just not show a download window. Not sure whether my browser or the server
// is doing this, but you might want to set the value of songdelayms high enough.

// The script is not really that useful, but it was fun to play around with this.
