It's interesting to see these lists as they show you which songs the general radio-listening public would recognise.
If Morrissey was to perform at a festival, these are probably the songs that would go down the best, or at least that most people would be able to sing along to.
Not surprisingly, the Marr contributions dominate although, less predictably, Alain's First of the Gang nearly takes the top spot.
The list shows Street in a pretty good light. He only wrote 5 singles for Morrissey, and 3 are in the top 15. That's probably a better strike rate than Marr.
It doesn't generally reflect well on Morrissey's post-Smiths repertoire. Nearly 4 times as many songs but it's still the Marr compositions that dominate.
I would argue this is partly due to consistently poor choice of single. Had he released his most melodic and catchiest songs over the years (e.g. Staircase, Now My Heart, Nobody Loves Us, When last I spoke to Carol, etc) I reckon the airplay list would be quite different.
Do it by album sales , say the first five years of release, and it comes out differently still. Add downloads or even do downloads and you get something different again perhaps by generation. Statistics are fun
