Truncated enqueuing of songs

[Sudesh]

If in a grooveshark playlist if one starts playing a song from middle of a playlist, then the previous button does not work beyond that song.(i.e If there are 10 songs , start playing playlist from 5th song , if pressed 'previous' for that song it doesn't move to 4th song).

Steps to reproduce:

1.Launch Moovida
2.Goto Internet media->Grooveshark
3.Start playing playlist from song 5th(or any song in middle)
4.Press previous

Expected Result : The 4th i.e previous song comes up.

Current Result : Nothing happens

I can confirm, and I can also observe the same bug when playing a selected song from an album.
