Michael Hobbs pointed out a few weeks back that the Cornell Laboratory of
Ornithology site has a pretty good library of bird songs. The song(s) of the
black-headed grosbeak can vary quite a bit but the sample at the link below
gives you a sense of how it sounds a bit like American Robin.

Take a listen and see if this sounds like what you heard.

>Walking in Seward Park Thursday I heard what I initially thought was a
>Robin, "Cheeri-o, Cheeri-up". But not quite right. Too high in the
>canopy, for one thing, and too, well, musical. Then it went into some
>lovely variations, each starting with the "Cheerio, cheeri-up", but
>going on to an amazing series of chirrups and trills. One series
>sounded like "Cheerio, cheeri-up, too weird, chirrup, so weird,
>trlllllll......"

>After listening and watching for about 10 minutes the author revealed
>itself briefly, to fly from one hidden perch to another high in a Doug
>Fir, but in silhouette (danged sunshine). Smaller than a Robin, thicker
>than a warbler, bigger than a kinglet. And then went silent.

>It reminded me in a way of the manner in which Ruby-crowned Kinglets
>sing seemingly to themselves in the early spring. On and on and on. OK.
>I'm stumped. Any ideas out there?

>Other summer voices in the park this last month: Olive-sided
>Flycatcher, Hutton's Vireo, Pacific-slope Fylcatcher, Townsend's
>Warbler, Yellow Warbler.
