music player - Force Media Update?

Sometimes I download songs from various sources, and they aren't put in the requisite media folder on external storage. The media scanner can still find them, but the only way I have found to do this is by moving the file around with a file manager, or mounting and unmounting as USB storage. This forces the phone to rescan for media files.

Does anyone know of a way to give Android a hint that it needs to rescan for media from within Android itself?

Answer

Most custom ROMs include this functionality as part of the Power Widget. For stock firmware you have to resort to 3rd-party apps such as ScanMedia or SDRescan, for example.
