Say Lou Lou
I reckon at least two of those will make the list
The first 4 on your list are what came to my mind too but I haven't been looking around for new artists for a while.
I did read an article the other day where it said the record labels are looking for young male acoustic singer-songwriter types because of the success of Ben Howard and Jake Bugg. The artists mentioned were Lewis Watson (meh), Hudson Taylor (meh) and Luke Sital-Singh (better) so one of them could be on the list.
