this exactly!! she seems so meh about her music career when it's what she needs to focus on since her acting career isn't happening at the moment. she needs to focus on launching her music career onto the next level.
The only reason her acting career isn't happening at the moment is because she's barely doing anything acting-related. Once she actually focuses on that, she could be huge with the right roles.
Selena is really competent on catching people attention on comercials if some seconds of a song in it can keep such song charting with almost zero radio play. Talent!
I think the acoustic version will just be a video of her perofrming it uploaded to VEVO, not an iTunes release.
But thats better, since she is slaying em streams.
