How to find out what J-Pop tracks are doing well in the UK

A bit of a how-to here. It's what I've come to rely on anyway to tell me what (reasonably) new stuff is doing the rounds on UK iTunes.

Firstly, there's the frustration that within iTunes main store, it's very difficult to actually access the J-Pop chart - it's lumped in with the 'World' chart and can typically only be seen when searching for 'related' content to albums actually flagged specifically as 'J-Pop'.

Thank God for iTop Chart then, who provide the data in a stripped-out, easy to access format.

Top 100 J-Pop Albums
Top 100 Anime Songs
Top 100 Anime Albums

Far from ideal, but better than nothing, right? I'm not sure why iTunes deems fit to separate J-Pop and Anime as two separate genres (and what determines whether a release is one or the other), but by sticking to these four charts, you can glean a reasonable insight into what's new - as these releases typically filter to the top.

Sadly, the 'Anime' charts are flooded with what I deem 'unofficial' tribute versions - to which the only answer can be 'Release the proper versions in the UK please!'
