I think it has more to do with how marketable she is as an artist,Tamar has several platforms that should've been used to promote her music and some of them have been used to promote her music.Tamar has been touring it seems like since Love&War,she's been on two reality shows,she was on DWTS, and she has the talk show.Tamar has also performed on on several televised award/shows. Being a great singer isn't enough, if that was the case she wouldn't have flopped in an era where true talent was still appreciated(The 90's), some people just aren't meant to sell that much. It doesn't mean she's not talented just means she's not marketable.She's had plenty of promo,people just weren't interested.There is only so much your label can do as far as promo goes, you'd think with her being everywhere she'd at least do 100K opening week.4 flops in a row now for her.
