I'm around the first three options only difference being I was actually afraid of misjudging and that I'd end up regretting not buying some of it, missing out on 'gems'. I don't think this has actually happened though... but let's say for example; a year from now Shiina wakes up bumping her head hard and coming up with a brilliant rock album some 5 months later thinking she's a rock star. I might miss the gap between Variety and 'Hypothetical Xcstacy
*' :<
Note: Sanmon Gossip for example is really good, but only kind of, but it was during a phase in my life where I felt too dissappointed by her work. I never spoke ill about it but it just wasn't my cup of tea at all I guess. Shun was really great and I'd probably rather buy it as a single than the album.
Edit: Ariamaru Tomi is one of my favourite SR songs of all time
