It is unfortunate that the supercell is not tagged with a lower case 's' but the fact is, it is spelled correctly and it holds the VAST majority of the listeners (to the tune of 126878 : 646 which means that the stylised tag has around 0.5% of the listeners of the unstylised one). In the interest of keeping stats tidy and scrobbles in one place it would be best to accept that supercell with the traditional typefont is the correct tag. The lack of stylisation is NOT a reason to consider this an incorrect tag. To link the relatively unused tag has no other effect than to split last.fm users. Please refrain from doing this.
