Something pretty similar happened to me too.
My husband asked how it went (as the whole thing) and I said it was great, and there were some wonderful pieces of music. And then I had to revise my statement, as I realised that made it sound like some weren't wonderful It's really great to look at the programme and see 35+ performances and realise every single one was enjoyable to listen to.
It's also good because there are some things you just don't listen to - see, for example, the thread about music you know you 'ought' to like but don't. There are some things where if I were invited to a three hour concert of X (= composer, genre, etc), I would decline. However, this format has two good things:
1) Five minutes of almost anything is at the very least bearable. I mean, even if it was something you really didn't like, you could probably sit through five minutes of it (with obvious exceptions, say someone was making that noise that always triggers your migraines for five minutes, that probably wouldn't be bearable!!)
2) It does make you realise that you can't really make such sweeping statements as "I despise all X" when you discover you have just listened to and enjoyed a five minute 'dose' of it
