The charts have always been full of sh*t at any given point; people just tend to focus on the stuff the liked and knew when looking back.
Re: BMTH, with respect, I don’t think there’s much merit spending time speculating on bands you don’t really know much about.
This is an actual dream. I've wanted to see them live again ever since I saw them support Stevie Wonder in 2010. And in Scotland, too - amazing! Take my money!!!
1. I would try to log on to hit the pre-queue waiting room as early as possible; there is no evidence to show this helps, but at least you know you did everything you could. On Thursday the pre-queue waiting room opened about 1 hour before the sale and showed a countdown timer. I'd aim for 8am.
2. No need for multiple tabs; each tab will share the same queue ID. So I'd advise not to bother with multiple tabs as it'll only cause you possible hassle. Multiple browsers or separate browser sessions (i.e. incognito + non-incognito) appear to get separate queue IDs, but the effect on whether the system sees you more likely as a bot is unknown. Personally, I wouldn't risk it for the marginal advantage it might give you, but it's totally up to you.
3. There is no need to refresh once you are in the pre-queue waiting room and/or the actual queue. Instead of refreshing, you should utter some affirmations of patience and/or have a little pray to the Glasto gods while you're waiting for the green bar to grow. If your F5 finger needs something to do, you can refresh this site, which will almost certainly be having issues itself -- it was on Thursday!
4. There is no body of evidence that queueing on your phone is any better than queueing using any other kind of device, but I would definitely advise queueing on your phone on 4G/5G/whatever regardless in addition to whatever broadband/wifi device you might be using. That definite counts as a different queue ID and comes from a different IP address, which is definitely giving you another shot.
The very best of luck!
