The Lumineers won't make it to number one on Hot 100. TS is too huge in streaming anyway. Number two is possible though. Which would be interesting, to have three #2s so soon in the year. (If S&S makes it there this week, that is...)
Ho Hey is #3 on the On Demand chart and they still have an airplay lead so you never know. Not likely but possible -they'd need to go out to a huge massive lead right now though and keep it through the week. I don't think the momentum will carry through the next week considering the strength of Thrift Shop.
